Pavel Begunkov 6a91a5816b io_uring: always lock __io_cqring_overflow_flush ...

commit 8d09a88ef9d3cb7d21d45c39b7b7c31298d23998 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.
