cluster/afr: Don't start heal when lookup succeeds on < 2 children
Problem: When self-heal code doesn't see at least 2 successes on looking up children, then self-heal can't be done. What is happening now is if all the lookups fail then the pending changelog is all zeros in xattrs so all the children are becoming sources and leading to crashes when the code paths further assume that some data structures are populated properly Fix: Don't proceed with self-heals when < 2 children succeed lookups.
