Gabriel Krisman Bertazi 84f904f031 fsnotify: Protect fsnotify_handle_inode_event from no-inode events 
[ Upstream commit 24dca90590509a7a6cbe0650100c90c5b8a3468a ]

FAN_FS_ERROR allows events without inodes - i.e. for file system-wide
errors.  Even though fsnotify_handle_inode_event is not currently used
by fanotify, this patch protects other backends from cases where neither
inode or dir are provided.  Also document the constraints of the
interface (inode and dir cannot be both NULL).
