VMWare Workstation NVMe emulation does not seem to write the
SHST_COMPLETE bit within 10 seconds, resulting in an ERRLOG
during detach/shutdown. So add a quirk to cover these VMWare
SSDs. But rather than squashing the ERRLOG completely for
these SSDs, just add a message instead indicating this is
somewhat expected on these VMWare emulated SSDs.

This value was not being decremented when we got SEND completions for
write operations because we were using the recv send to indicate when we
had completed all writes associated with the request. I also erroneously
made the assumption that spdk_nvmf_rdma_request_parse_sgl would properly
reset this value to zero for all requests. However, for requests that
return SPDK_NVME_DATA_NONE rom spdk_nvmf_rdma_request_get_xfer, this
funxtion is skipped and the value is never reset. This can cause a
coherency issue on admin queues when we request multiple log files. When
the keep_alive request is resent, it can pick up an old rdma_req which
reports the wrong number of outstanding_wrs and it will permanently
increment the qpairs curr_send_depth.
This change decrements num_outstanding_data_wrs on writes, and also
resets that value when the request is freed to ensure that this problem
doesn't occur again.

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.

Existing specific vhost socket messages for vhost-nvme target
will get some information from backend target before start_session
call, so we should iterate the associated nvme controller by vid
but not session.
Fix issue #628.

Error check of strtol is left to users of it. But some use cases
of strtol in SPDK do not have enough error check yet.
For example, strtol returns 0 if there were no digits at all.
It should be avoided for each use case to add enough error checking
for strtol.
Hence spdk_strtol and spdk_strtoll do additional error checking
according to the description of manual of strtol.
Besides, there is no use case of negative number now, and to keep
simplicity, spdk_trtol and spdk_strtoll allows only strings that
is positive number or zero.
As a result of this policy, callers of them only have to check if
the return value is not negative.
Subsequent patches will replace atoi to spdk_strtol because atoi
does not have error check.
