IB/ipoib: Fix packet loss after hardware address update
The neighbour ha field may get updated without destroying the
neighbour. In this case, the ha field gets out of sync with the
address handle stored in ipoib_neigh->ah, with the result that
the ah field would point to an incorrect path, resulting in all
packets being lost.
