[PATCH net-next] tcp: Remove unused function declarations

[PATCH net-next] tcp: Remove unused function declarations

[Yue Haibing]

commit 8a59f9d1e3d4 ("sock: Introduce sk->sk_prot->psock_update_sk_prot()")
left behind tcp_bpf_get_proto() declaration. And tcp_v4_tw_remember_stamp()
function is remove in ccb7c410ddc0 ("timewait_sock: Create and use getpeer op.").
Since commit 686989700cab ("tcp: simplify tcp_mark_skb_lost")
tcp_skb_mark_lost_uncond_verify() declaration is not used anymore.
