Building with CONFIG_IPV6 off causes this build error

br_input.c:135:8: error: too many arguments to function
        br_multicast_is_router(br, skb)) {
In file included from net/bridge/br_input.c:23:
net/bridge/br_private.h:1059:20: note: declared here
 static inline bool br_multicast_is_router(struct net_bridge *br)

Comparing the stub with the real function shows the stub needs
another parameter.
