In case of an error, ublk's ->uring_cmd() functions currently return
-EIOCBQUEUED and immediately call io_uring_cmd_done(). -EIOCBQUEUED and
io_uring_cmd_done() are intended for asynchronous completions. For
synchronous completions, the ->uring_cmd() function can just return the
negative return code directly. This skips io_uring_cmd_del_cancelable(),
and deferring the completion to task work. So return the error code
directly from __ublk_ch_uring_cmd() and ublk_ctrl_uring_cmd().

Applied, thanks!
