Jens Axboe aa96bf8a9e io_uring: use io-wq manager as backup task if task is exiting ...

If the original task is (or has) exited, then the task work will not get
queued properly. Allow for using the io-wq manager task to queue this
work for execution, and ensure that the io-wq manager notices and runs
this work if woken up (or exiting).
