nvme-fabrics: refactor queue ready check
Move the is_connected check to the fibre channel transport, as it has no
meaning for other transports. To facilitate this split out a new
nvmf_fail_nonready_command helper that is called by the transport when
it is asked to handle a command on a queue that is not ready.
Also avoid a function call for the queue live fast path by inlining
the check.
