[PATCH 2/2] bridge: fix compile error when compiling without IPv6 support

[Linus LÃssing]

Some fields in "struct net_bridge" aren't available when compiling the
kernel without IPv6 support. Therefore adding a check/macro to skip the
complaining code sections in that case.

Introduced by 2cd4143192e8c60f66cb32c3a30c76d0470a372d
("bridge: memorize and export selected IGMP/MLD querier port")

Reported-by: kbuild test robot <fengguang.wu@xxxxxxxxx>
