[GIT PULL] io_uring fix for 6.19-rc5

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Single fix for a regression introduced in 6.15, where a failure to wake
up idle io-wq workers at ring exit will wait for the timeout to expire.
This isn't normally noticeable, as the exit is async. But if a parent
task created a thread that sets up a ring and uses requests that cause
io-wq threads to be created, and the parent task then waits for the
thread to exit, then it can take 5 seconds for that pthread_join() to
succeed as the child thread is waiting for its children to exit.

On top of that, just a basic cleanup as well.

Please pull!
