wireguard: selftests: initalize ipv6 members to NULL to squelch clang warning
commit 169e8bbc1d39088a46931e5edbb7ad6bb75616d3 upstream.
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:
drivers/net/wireguard/selftest/ratelimiter.c:173:34: error: variable 'skb6' is uninitialized when used here [-Werror,-Wuninitialized]
ret = timings_test(skb4, hdr4, skb6, hdr6, &test_count);
^~~~
drivers/net/wireguard/selftest/ratelimiter.c:123:29: note: initialize the variable 'skb6' to silence this warning
struct sk_buff *skb4, *skb6;
^
= NULL
drivers/net/wireguard/selftest/ratelimiter.c:173:40: error: variable 'hdr6' is uninitialized when used here [-Werror,-Wuninitialized]
ret = timings_test(skb4, hdr4, skb6, hdr6, &test_count);
^~~~
drivers/net/wireguard/selftest/ratelimiter.c:125:22: note: initialize the variable 'hdr6' to silence this warning
struct ipv6hdr *hdr6;
^
We silence this warning by setting the variables to NULL as the warning
suggests.
