tcp: Remove sk->sk_prot->orphan_count.
TCP tracks the number of orphaned (SOCK_DEAD but not yet destructed)
sockets in tcp_orphan_count.
In some code that was shared with DCCP, tcp_orphan_count is referenced
via sk->sk_prot->orphan_count.
Let's reference tcp_orphan_count directly.
inet_csk_prepare_for_destroy_sock() is moved to inet_connection_sock.c
due to header dependency.
