When a connection goes to close and has no I/O outstanding,
the current_recv_depth was being decremented beyond 0 and rolling over.
If the poll group then finds a successful receive completion on the next
poll (for a command that arrived prior to starting the disconnect but
hadn't been processed yet), it would trip the max queue depth check
added recently and start another disconnect process. If only one command
arrives in this window, everything actually works out ok.
However, if there are two receive completions sitting in the completion
queue after the disconnect process is started, the first one does the
double disconnect and the second one does another disconnect which ends
up dereferencing a null pointer.
Since there is always a special reserved slot for the dummy recv, don't
do decrements or increments of the current_recv_depth for the dummy
recv. This allows the code to still enforce the actual max_queue_depth
on recvs without underflowing or overflowing the counter.

rw_depth was a misinterpretation of the spec. It is based on the value
of max_qp_rd_atom which only governs the number of read and atomic
operations. However, we were using rw_depth to block both read and write
operations which is an unnecessary restriction. write operations should
only be governed by the number of Work Requests posted to the send
queue. We currently guarantee that we will never overshoot the queue
depth for Work requests since they are embedded in the requests and
limited to a size of max_queue_depth.

This change is related to enabling multi-sgl element support in
the NVMe-oF target.
For single SGL use cases, there is a 1:1 relationship between
rdma_requests and ibv_wrs used to transfer the data associated with
the request. In the ingle SGL case that ibv_wr is embedded inside of
the spdk_nvmf_rdma_request structure as part of an rdma_request_data
structure.
However, with Multi-SGL element support, we require multiple
ibv_wrs per rdma_request. Insted of embedding these
structures inside of the rdma_request and bloating up that object, I
opted to leave the first one embedded in the object and create a pool
that requests can pull from in the Multi-SGL path.
By leaving the first request_data object embedded in the rdma_request
structure, we avoid adding the latency of requesting a mempool object
in the basic cases.

We have historically conflated SPDK_NVMF_MAX_SGL_ENTRIES and the maximum
number of SGEs associated with a wr data object. For now these are the
same thing, but there should be nothing tying the number of NVMe request
SGL elements to the number of rdma request wr sgl elements.
Also, clarify the rx_sge and tx_sge enums to reflect the actual maximum
number of SGEs associated with either the send and receive queues.
This change doesn't actually modify these values, but sets us up to do
things like split the data in an NVMe SGE into multiple WR SGEs in case
the buffer associated with the NVMe SGE is not contained in a single
RDMA mr.
We also need to store these values in the qpair for later usage.

2. Post dummy work requests to send and receive queues
3. Poll CQ until it returns dummy work requests (with WR Flush Error status)
4. Call ibv_destroy_qp and release resources
In order to differentiate dummy and normal WRs new spdk_nvmf_rdma_wr
structure was introduced which contains type of WR. Since now it is
expected that wr_id field in ibv_recv/send_wr and ibv_wc always points
to this structure. Based on WR type wr_id can be safely casted to
correct container structure. In case of unsuccessful work completions
'opcode' can not be used for this purpose because it may be
invalid (see "IB Architecture Specification Volume 1", ch. 11.4.2.1

This function will now check for whether or not a memory region is
contiguous accross 2MB map entries and return the total length of that
contiguous buffer up to the size specified by the user.
Also includes unittests
This series of changes is aimed at enabling spdk_mem_map_translate to
report back to the user the length of the valid mem_map up to the

This will be useful when retrieving memory regions associated with I/O

In RDMA, qpairs can't be removed from poll groups because
the poll group defines the completion queue. So don't
allow this operation anymore, even if it were theoretically

IBV_EVENT_SQ_DRAINED can occur during both error recovery and
normal operation. We don't want to spend time sending a message
to the correct qpair thread and then attempting to abort
all I/O in the case where this wasn't triggered by an error.
The case where this occurs during an error is very rare and
only in response to a user forcing the state to err from the
sqd state. For now, don't handle that case at all. Handle that
corner case in a later patch.

At times, it may be necessary to free requests without completing them.
For example, when freeing a qpair, one needs to free the AER sent from
the host before deleting the qpair. It is important not to send a
completion for the AER because:
1. According to the spec, this will trigger the host to send another AER
2. No Asynchronous Events have occured, so we should not complete the
AER.

RDMA QP is attempted to recover after IBV_EVENT_QP_FATAL event
is received from IBV asynchronous event API.
RDMA QP is put into ERROR state and is not processing any inbound
requests. The outstanding requests are only allowed to COMPLETED
and FREE states, no outbound transfers are performed.
IBV_EVENT_QP_LAST_WQE_REACHED or IBV_EVENT_SQ_DRAINED event is
expected to follow IBV_EVENT_QP_FATAL, giving a go to draining of
all outstanding requests and freeing the associated resources.
The requests executed by block layer are gracefully allowed to
complete, but no outbound transfers are made.
Note, outstanding requests can not be reliably completed through
polling the CQ, as WC's with failure status might not have all
the fields valid. The failed WC's are dropped and the outstanding
requests are fetched from the appropriate state's linked list.
QP recovery is triggered when there is no more outstanding requests.
If QP recovery is completed succesfully, the RDMA QP is put back into
ACTIVE state, the QP disconnect is triggered otherwise.

Requests that are being put into IBV context are lost when
IBV QP breaks and its SQ drains.
In order to track NVMf/RDMA requests, RDMA QP has been
reworked to track requests at any state with queues of
requests for each state.
This allowed to get rid of a few intermediate queues and
request counters.
A couple of states has been added to track outbound requests
with and without data. They will be used by QP recovery for
freeing resources assigned to outstanding requests.
