io_uring: fix missing io_queue_linked_timeout()
Whoever called io_prep_linked_timeout() should also do
io_queue_linked_timeout(). __io_queue_sqe() doesn't follow that for the
punting path leaving linked timeouts prepared but never queued.
Fixes: 6df1db6b54243 ("io_uring: fix mis-refcounting linked timeouts")
