[PATCH 1/3] io_uring: fix mshot io-wq checks

[Pavel Begunkov <asml.silence@gmail.com>]

When checking for concurrent CQE posting, we're not only interested in
requests running from the poll handler but also strayed requests ended
up in normal io-wq execution. We're disallowing multishots in general
from io-wq, not only when they came in a certain way.

Fixes: 17add5cea2bba ("io_uring: force multishot CQEs into task context")
