io_uring/uring_cmd: skip io_uring_cmd_issue_blocking() task work

Browse source

io_uring_cmd_issue_blocking() is only called from blk_cmd_complete(),
which is already a task work callback. However, it queues another task
work item, to call io_queue_iowq(). Just call io_queue_iowq() directly
to skip the CPU cost and latency of the redundant task work proxying.
