autofs: change autofs4_expire_wait()/do_expire_wait() to take struct path
In order to use the functions path_is_mountpoint() and path_has_submounts()
autofs needs to pass a struct path in several places.
Start by changing autofs4_expire_wait() and do_expire_wait() to take
a struct path instead of a struct dentry.
