io_uring/uring_cmd: take advantage of completion batching 



We know now what the completion context is for the uring_cmd completion
handling, so use that to have io_req_task_complete() decide what the
best way to complete the request is. This allows batching of the posted
completions if we have multiple pending, rather than always doing them
one-by-one.
