AP MLD: Fix SA query timeout during MLD reassociation

If an AP MLD receives a (Re)Association Request frame from an associated
non-AP MLD and if SA query has already timed out for the existing
station entry, the link address should be updated since the non-AP MLD
might have changed its link address in the new association.
