dnotify: ignore FS_EVENT_ON_CHILD ...
Mask off FS_EVENT_ON_CHILD in dnotify_handle_event(). Otherwise, when there
is more than one watch on a directory and dnotify_should_send_event()
succeeds, events with FS_EVENT_ON_CHILD set will trigger all watches and cause
spurious events.
This case was overlooked in commit e42e2773.
