io_uring: fix task_work cap overshooting
A previous commit fixed task_work overrunning by a lot more than what
the user asked for, by adding a retry list. However, it didn't cap the
overall count, hence for multiple task_work runs inside the same wait
loop, it'd still overshoot the target by potentially a large amount.
Cap it generally inside the wait path. Note that this will still
overshoot the default limit of 20, but should overshoot by no more than
limit-1 in addition to the limit. That still provides a ceiling over how
much task_work will be run, rather than still having gaps where it was
uncapped essentially.
