Jens Axboe 30dab608c3 io_uring/futex: always remove futex entry for cancel all ...

We know the request is either being removed, or already in the process of
being removed through task_work, so we can delete it from our futex list
upfront. This is important for remove all conditions, as we otherwise
will find it multiple times and prevent cancelation progress.
