io_uring: don't cancel extra on files match
As tasks always wait and kill their io-wq on exec/exit, files are of no more concern to us, so we don't need to specifically cancel them by hand in those cases. Moreover we should not, because io_match_task() looks at req->task->files now, which is always true and so leads to extra cancellations, that wasn't a case before per-task io-wq.
