fsnotify: introduce locked versions of fsnotify_add_mark() and fsnotify_remove_mark()

Browse Source 
This patch introduces fsnotify_add_mark_locked() and fsnotify_remove_mark_locked()
which are essentially the same as fsnotify_add_mark() and fsnotify_remove_mark() but
assume that the caller has already taken the groups mark mutex.
