Subject: [PATCH net-next] net/ip6mr: Fix build with !CONFIG_IPV6_PIMSM_V2

The following build-error on my config:
net/ipv6/ip6mr.c: In function ‘ip6_mroute_setsockopt’:
net/ipv6/ip6mr.c:1656:14: error: unused variable ‘do_wrmifwhole’ [-Werror=unused-variable]
 1656 |         bool do_wrmifwhole;
      |              ^
