xfs: don't try to scrub self-referential dirent in metapath checker
LOLLM observes that the _ilock_both helper will loop forever trying to
double-lock the same inode if mpath->dp == sc->ip. Callers are not
supposed to call us with parent == child because that makes no sense.
Trigger an assertion, mark the scan incomplete, and return IO error
so that this fails noisily.
