fsnotify: dont put marks on temporary list when clearing marks by group
In clear_marks_by_group_flags() the mark list of a group is iterated and the marks are put on a temporary list. Since we introduced fsnotify_destroy_mark_locked() we dont need the temp list any more and are able to remove the marks while the mark list is iterated and the mark list mutex is held.
