[IPV6] MLDv2: fix change records when transitioning to/from inactive

The following patch fixes these problems in MLDv2:

1) Add/remove "delete" records for sending change reports when
        addition of a filter results in that filter transitioning to/from
        inactive. [same as recent IPv4 IGMPv3 fix]
2) Remove 2 redundant "group_type" checks (can't be IPV6_ADDR_ANY
        within that loop, so checks are always true)
3) change an is_in() "return 0" to "return type == MLD2_MODE_IS_INCLUDE".
        It should always be "0" to get here, but it improves code locality 
        to not assume it, and if some race allowed otherwise, doing
        the check would return the correct result.
