[PATCH 1/1] io_uring/timeout: fix multishot updates

[Pavel Begunkov <asml.silence@gmail.com>]

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.
