bridge br_multicast: Don't refer to BR_INPUT_SKB_CB(skb)->mrouters_only without IGMP snooping.
Without CONFIG_BRIDGE_IGMP_SNOOPING, BR_INPUT_SKB_CB(skb)->mrouters_only is not appropriately initialized, so we can see garbage. A clear option to fix this is to set it even without that config, but we cannot optimize out the branch. Let's introduce a macro that returns value of mrouters_only and let it return 0 without CONFIG_BRIDGE_IGMP_SNOOPING. Signed-off-by:YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by:
