Two small bug fixes. The first fix is for a real issue that encountered
on 5.13, which caused my workload not to work with a submission queue.
Apparently, on 5.14 it is only a performance issue (i.e., not a
functionality issue).

The second fix is for a theoretical issue.

I did not cc stable, as I leave this decision to the maintainer.

io_uring: clear TIF_NOTIFY_SIGNAL when running task work
io_uring: Use WRITE_ONCE() when writing to sq_flags
