fsnotify, lsm: Decouple fsnotify from lsm

Browse Source 
Currently, fsnotify_open_perm() is called from security_file_open().
This is a a bit unexpected and creates otherwise unnecessary dependency
of CONFIG_FANOTIFY_ACCESS_PERMISSIONS on CONFIG_SECURITY. Fix this by
calling fsnotify_open_perm() directly.
