zebra: Prevent crash in dad auto recovery

Commit: 6005fe55bce1c9cd54f4f7773fc2b0e15a99008f
Introduced a crash with zebra looking up either the
nbr structure or the mac structure.  This is because
the zvni used is NULL and we eventually call a hash_lookup
call that would cause a NULL dereference.  Partially
revert this commit to original behavior.

Problems found via clang Static Analyzer.
