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. Signed-off-by: Jens Axboe <axboe@kernel.dk>
