Bug 8539: IPv6 L3 Forwarding broken.

The merge of the following review;
https://git.opendaylight.org/gerrit/57145
broke L3 Forwarding for IPv6 addressed ports.

The fix here addresses the breakage by making
sure that L3_GW_MAC_TABLE entries are filled
correctly for both IPv4 and IPv6 router-interface
ports, before embarking on writing PING
Responder flows for IPv4 based router-interfaces.
