bpf: tcp: Fix type confusion in bpf_skc_to_tcp_sock().
bpf_skc_to_tcp_sock() only checks if sk->sk_protocol is
IPPROTO_TCP, but RAW socket can bypass it:
socket(AF_INET, SOCK_RAW, IPPROTO_TCP)
Let's use sk_is_tcp().
Fixes: 478cfbdf5f13 ("bpf: Add bpf_skc_to_{tcp, tcp_timewait, tcp_request}_sock() helpers")
