inotify: don't leak user struct on inotify release
inotify_new_group() receives a get_uid-ed user_struct and saves the reference on group->inotify_data.user. The problem is that free_uid() is never called on it. Issue seem to be introduced by 63c882a0 (inotify: reimplement inotify using fsnotify) after 2.6.30.
