Subject: [PATCH] io_uring: simplify io_uring_cmd return
We don't have to return error code from an op handler back to core
io_uring, so once io_uring_cmd() sets the results and handles errors we
can juts return IOU_OK and simplify the code.
Note, only valid with e0b23d9953b0c ("io_uring: optimise ltimeout for
inline execution"), there was a problem with iopoll before.
