io_uring: flush overflowed CQ events in the io_uring_poll()

Browse source

[ Upstream commit 63e5d81f72 ]

In io_uring_poll() we must flush overflowed CQ events before to
check if there are CQ events available, to avoid missing events.

We call the io_cqring_events() that checks and flushes any overflow
and returns the number of CQ events available.
