[IPV6] MCAST: Ensure to check multicast listener(s).
In ip6_mc_input(), we need to check whether we have listener(s) for
the packet.
After commit ae7bf20a6316272acfcaef5d265b18aaa54b41e4, all packets
for multicast destinations are delivered to upper layer if
IFF_PROMISC or IFF_ALLMULTI is set.
In fact, bug was rather ancient; the original (before the commit)
intent of the dev->flags check was to skip the ipv6_chk_mcast_addr()
call, assuming L2 filters packets appropriately, but it was even not
true.
Let's explicitly check our multicast list.
