The queue type and queue depth are not known until
the connect capsule is processed. Delay allocating more
than 1 recv wqe until then.

Currently, the recv wqe is re-posted immediately. This
closes a small window where we could get more I/O
than we could handle.

When Debug is not defined, SPDK_TRACELOG will do nothing,
thus cmd_type is an unused variable, and will trigger the
compilation warnings. And this patch will solve this issue

NVMe over Fabrics defines its own NVMe Qualified Name (NQN) format; it
does not use iSCSI Qualified Names.
Also change the default node base for nvmf_tgt to "nqn.2016-06.io.spdk".

Drop the RDMA-specific fields from spdk_nvmf_request and get them
directly from the command SGL in the transport-specific read function.

If an invalid SGL is specified, send a response with a status code
indicating what the error was rather than silently dropping the command.

The "immediate completion" cases in spdk_nvmf_request_exec() already
call spdk_nvmf_request_complete(), so the ret == 1 case in nvmf_recv()
is bogus.
Also fix a couple of spdk_nvmf_request_complete() calls in
nvmf_process_admin_cmd() that should be handled by its caller.

These are not supported (and did not actually function) in NVMe over

This fixes an oversight that allowed in-capsule data block SGLs to
potentially refer to more than the received in-capsule data size.
It also makes spdk_nvmf_request_prep_data() less dependent on the
RDMA-specific rx_desc/tx_desc structures.
