responder_resources parameter of rdma cm tells remote
side how many outstaing RDMA_READ of atomic operations
local side can handle.
Previously it was adjusted on queue depth but that was
not correct since these parameters do not depend on
each other. Even with qdepth=1 remote side may send
several RDMA_READ operations per 1 IO request.
With this change we report responder_resources
equal to the maximum supported by RDMA device.
Linux kernel nvme rdma driver reports this value
in the same way.

SPDK_TRACE_ARG_TYPE_INT arguments, it will call va_arg(vl, uint64_t)
to get value. However, if the submitted type is not uint64_t,
va_arg may return outlier.
To solve the problem, the parameter should be converted into

start, is the path specified by the user).
Additional entries are added for discovery log page

When the discovery service starts, we just have the
initial entry in the list - the discovery poller
tries to connect to it, and if the connect starts
successfully, removes it from the list and points
ctx->entry_ctx_in_use to it.
This will be useful later when we want to iterate

We used to wait until the discovery service could
connect to the discovery subsystem before calling
the callback function provided by the caller (mainly
the start_discovery RPC).
Moving forward, we will be handling the case where
the discovery subsystem is unavailable temporarily.
For now, let's not fail the bdev_nvme_start_discovery
call if we cannot connect to the discovery subsystem.
This will keep the initial service start path the same
as the path where the discovery subsystem is temporarily
unavailable. In the future, we can consider adding
functionality to the start_discovery RPC that waits
up to X number of seconds to see if we were able to
connect and fail otherwise.

The feature will be redesigned and restored in the following patches.
For the NVMe bdev module, it can reconnect by itself without relying
on the feature.

For nvme_rdma_qpair_process_completions(), consolidate the operations to
call nvme_rdma_fail_qpair() and return -ENXIO into a single place.
Besides, shorten pointer references for
nvme_rdma_qpair_process_completions() and
nvme_rdma_poll_group_process_completions().
These will make the following patches a little easier.

Add a new flag is_disconnecting to struct spdk_nvme_ctrlr.
Separate calling nvme_ctrlr_disconnect() and nvme_ctrlr_disconnect_done()
by using the flag is_disconnecting.
Additionally, change nvme_ctrlr_fail() to skip setting ctrlr->is_failed
to true if ctrlr->is_disconnecting is true.

nvme_transport_ctrlr_connect_qpair() calls
nvme_transport_ctrlr_disconnect_qpair() if failed.
If async qpair disconnect is supported, even when connect qpair failed,
nvme_transport_ctrlr_connect_qpair() may complete asynchronously later.
The cases that qpair->async is set to true are I/O qpair for the NVMe
bdev module and admin qpair.
example/nvme/perf and example/nvme/reconnect use I/O qpair but both
set qpair->async to false.
For the NVMe bdev module, I/O qpair is connected when creating I/O
channel or resetting ctrlr. If spdk_nvme_ctrlr_connect_io_qpair()
returns 0 for a I/O qpair, the qpair is in a poll group and is polled
by spdk_nvme_poll_group_process_completions() and a disconnected
callback is called to the qpair. Hence we do not need to add additional
polling for I/O qpair in the NVMe bdev module.

Serparate spdk_nvme_ctrlr_disconnect() into nvme_ctrlr_disconnect()
and nvme_ctrlr_disconnect_done() to call nvme_ctrlr_disconnect_done()
after adminq is actually disconnected when disconnecting adminq
asynchronously.
The following patches will add a new flag is_disconnecting to struct
spdk_nvme_ctrlr and prevent us from setting ctrlr->is_failed to true
between nvme_ctrlr_disconnect() and nvme_ctrlr_disconnect_done().
By this patch, nvme_ctrlr_disconnect() and nvme_ctrlr_disconnect_done()
are executed in the same context. So it is not possible to set
ctrlr->is_failed to true between nvme_ctrlr_disconnect() and
nvme_ctrlr_disconnect_done().
Hence nvme_ctrlr_disconnect_done() does not have to clear ctrlr->is_failed
again.
