io_uring: only wait for in-flight requests if the closing task uses the ring

Since commit 13d3783a55b7 ("io_uring: wait for in-flight requests on
ring release"), the task dropping the last reference to a ring waits
for every request on it to complete. A process that only received the
ring fd, e.g. over a UNIX socket, can then block in close(2) on
requests owned by other tasks, such as a read from an unresponsive
FUSE server.

Skip the wait for tasks that never attached to the ring and leave those
requests to io_ring_exit_work(), as before.
