xfs_repair: fix incorrect dabtree hashval comparison

If an xattr structure contains enough names with the same hash value to
fill multiple xattr leaf blocks with names all hashing to the same
value, then the dabtree nodes will contain consecutive entries with the
same hash value.

This causes false corruption reports in xfs_repair because it's not
expecting such a huge same-hashing structure.  Fix that.
