io_uring: fix mshot io-wq checks
[ Upstream commit 3a96378e22cc46c7c49b5911f6c8631527a133a9 ]
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.
