minios: Fix xenbus_unwatch_path calls
In a lot of places in MiniOS frontends, xenbus_watch_path_token is
used instead of xenbus_watch_path to get more precise wake ups. To
free those, xenbus_unwatch_path_token has to be used instead of
xenbus_unwatch_path, else the unwatch operation will fail. This fixes
spurious watch events left by pv-grub.
