[ Upstream commit d052d1d685f5125249ab4ff887562c88ba959638 ]
We bypass IOPOLL completion polling (and reaping) for the SQPOLL thread,
but if it's the thread itself invoking cancelations, then we still need
to perform it or no one will.
Fixes: 9936c7c2bc76 ("io_uring: deduplicate core cancellations sequence")
