io_uring: don't cancel all work on process exit
If we're sharing the ring across forks, then one process exiting means that we cancel ALL work and prevent future work. This is overly restrictive. As long as we cancel the work associated with the files from the current task, it's safe to let others persist. Normal fd close on exit will still wait (and cancel) pending work.
