UPSTREAM: io_uring: kill goto error handling in io_sqpoll_wait_sq()

Browse Source 
Hunk extracted from commit 70aacfe661
upstream.

If the sqpoll thread has died, the out condition doesn't remove the
waiting task from the waitqueue. The goto and check are not needed, just
make it a break condition after setting the error value. That ensures
that we always remove ourselves from sqo_sq_wait waitqueue.
