fsnotify: optimize the case of no marks of any type

Browse source

Add a simple check in the inline helpers to avoid calling fsnotify()
and __fsnotify_parent() in case there are no marks of any type
(inode/sb/mount) for an inode's sb, so there can be no objects
of any type interested in the event.
