bpf, tcp: Make tcp_bpf_recvmsg static

Browse Source 
After commit f747632b60 ("bpf: sockmap: Move generic sockmap
hooks from BPF TCP"), tcp_bpf_recvmsg() is not used out of
tcp_bpf.c, so make it static and remove it from tcp.h. Also move
it to BPF_STREAM_PARSER #ifdef to fix unused function warnings.

Fixes: f747632b60 ("bpf: sockmap: Move generic sockmap hooks from BPF TCP")
