  northd: reduce number of nd_na lb logical flows

As it has been already done for IPv4, collapse IPv6 Neighbour
Advertisment flows for load balancer using address list and
reduce the number of logical flows from N*M to N where N is
the number of logical router port and M is the number of
Virtual IPs.
