  Log Message:
  ovn-northd: Skip conntrack for MLD packets.

We currently skip conntrack for IPv6 Neighbor Discovery packets because
conntrack marks all ND packets as invalid [0].

The same thing should be done for MLD packets. Otherwise, as soon as an
allow-related ACL or load balancer is added, MLD packets will go to
conntrack and get dropped because they are marked "invalid".

This commit also fixes the MLD test to use a link local IPv6 source
