bridge br_multicast: Ensure to initialize BR_INPUT_SKB_CB(skb)->mrouters_only.
Even with commit 32dec5dd0233ebffa9cae25ce7ba6daeb7df4467 ("bridge br_multicast: Don't refer to BR_INPUT_SKB_CB(skb)->mrouters_only without IGMP snooping."), BR_INPUT_SKB_CB(skb)->mrouters_only is not appropriately initialized if IGMP snooping support is compiled and disabled, so we can see garbage.
