tcp: add declarations to avoid warnings

Remove these errors:

net/ipv6/tcp_ipv6.c:1550:29: warning: symbol 'tcp_v6_rcv' was not declared. Should it be static?
net/ipv6/tcp_ipv6.c:1770:30: warning: symbol 'tcp_v6_early_demux' was not declared. Should it be static?

net/ipv6/tcp_ipv6.c:1550:29: warning: no previous prototype for 'tcp_v6_rcv' [-Wmissing-prototypes]
