Mike Christie 6fd0ce7972 tcmu: prep queue_cmd_ring to be used by unmap wq
In the next patches we will call queue_cmd_ring from the submitting
context and also the completion path. This changes the queue_cmd_ring
return code so in the next patches we can return a sense_reason_t
and also signal if a command was requeued.
