Client STA traffic stops when roaming between AP interfaces.
When there is a neighbor change, cmm receives RTM_DELNEIGH/RTM_NEWNEIGH
events triggering an update to the routing table. But because there is
no MAC change, the event is discarded without a routing table update.
This fix eliminates the MAC address check, since there can still be
a port change.
Fixes b/18904094
