io_uring: allow io-wq workers to exit when unused
io_uring keeps a per-task io-wq around, even when the task no longer has
any io_uring instances.
If the task previously used io_uring for file I/O, this can leave an
unrelated iou-wrk-* worker thread behind after the last io_uring
instance is gone.
When the last io_uring ctx is removed from the task context, mark the
io-wq exit-on-idle so workers can go away. Clear the flag on subsequent
io_uring usage.
