Pavel Begunkov 605d055452 io_uring: break out of iowq iopoll on teardown 
[ upstream commit 45500dc4e01c167ee063f3dcc22f51ced5b2b1e9 ]

io-wq will retry iopoll even when it failed with -EAGAIN. If that
races with task exit, which sets TIF_NOTIFY_SIGNAL for all its workers,
such workers might potentially infinitely spin retrying iopoll again and
again and each time failing on some allocation / waiting / etc. Don't
keep spinning if io-wq is dying.

Fixes: 561fb04a6a ("io_uring: replace workqueue usage with io-wq")
