Qing Li 6b7b44acd9 The code in rn_walktree_from() that checks if we backed up too far
did not stop at the right node. Change the backtracking check from
smaller-than to smaller-or-equal to prevent this from happening.
While here fix one additional problem where the insertion of the
default route traversed the entire tree.
