fsnotify/vfsmount: add fsnotify fields to struct vfsmount

This patch adds the list and mask fields needed to support vfsmount marks.
These are the same fields fsnotify needs on an inode.  They are not used,
just declared and we note where the cleanup hook should be (the function is
not yet defined)
