  northd: fix FIP traffic with distributed gw router port on the same hv

If the hv has FIP assigned, traffic has to be sent out using the FIP
even if a distributed gw router port is scheduled on the local hv.
In this particular use-case without the proposed patch, the traffic
is sent out with FIP mac but using distributed gw router port IP.
