wireguard: selftests: initalize ipv6 members to NULL to squelch clang warning

Without setting these to NULL, clang complains in certain
configurations that have CONFIG_IPV6=n:

In file included from drivers/net/wireguard/ratelimiter.c:223:

We silence this warning by setting the variables to NULL as the warning
suggests.
