Pavel Begunkov 9f5a834715 io_uring: always lock __io_cqring_overflow_flush ...

Commit 8d09a88ef9 upstream.

Conditional locking is never great, in case of
__io_cqring_overflow_flush(), which is a slow path, it's not justified.
Don't handle IOPOLL separately, always grab uring_lock for overflow
flushing.
