getifaddrs: fix UB via taking address of null pointer union dereference
getifaddrs computes &ctx->first->ifa even if ctx->first is NULL. While this shouldn't be possible on the success path because the loopback interface is hardcoded into the kernel, this is still possible on the error path (for example, if __rtnetlink_enumerate couldn't create a socket due to exceeding the fd limit).
