bpf: tcp: Fix type confusion in bpf_skc_to_tcp6_sock().
bpf_skc_to_tcp6_sock() only checks if sk->sk_protocol is IPPROTO_TCP
and sk->sk_family is AF_INET6, but RAW socket can bypass it:
socket(AF_INET6, SOCK_RAW, IPPROTO_TCP)
Let's check sk->sk_type too.
Fixes: af7ec1383361 ("bpf: Add bpf_skc_to_tcp6_sock() helper")
