io_uring/timeout: fix multishot updates
commit c83c846231db8b153bfcb44d552d373c34f78245 upstream. After update only the first shot of a multishot timeout request adheres to the new timeout value while all subsequent retries continue to use the old value. Don't forget to update the timeout stored in struct io_timeout_data.
