io_uring: run cancelations synchronously on ring release

io_uring_release() just marks the ring as dying and punts everything
else to exit_work, including the cancelation of requests that are easily
cancelable right away Until that work has run, and the task_work it
generates has as well, those requests keep their files pinned. An
application that closes its ring and then expects the files it had been
using to be closed as well may be confused by this currently not being
the case.

Re-factor the cancelation pass out of io_ring_exit_work() and run it
directly from release, before punting the rest.
