io_uring: don't iopoll from io_ring_ctx_wait_and_kill()
[ Upstream commit 02bac94bd8efd75f615ac7515dd2def75b43e5b9 ]
We should not be completing requests from a task context that has already
undergone io_uring cancellations, i.e. __io_uring_cancel(), as there are
some assumptions, e.g. around cached task refs draining. Remove
iopolling from io_ring_ctx_wait_and_kill() as it can be called later
after PF_EXITING is set with the last task_work run.
