aio-posix: fix test-aio /aio/event/wait with fdmon-io_uring
When a file descriptor becomes ready we must re-arm POLL_ADD. This is
done by adding an sqe to the io_uring sq ring. The ->need_wait()
function wasn't taking pending sqes into account and therefore
io_uring_submit_and_wait() was not being called. Polling for cqes
failed to detect fd readiness since we hadn't submitted the sqe to
io_uring.
This patch fixes the following tests/test-aio -p /aio/event/wait
failure:
ok 11 /aio/event/wait
