tcp: Move skb_steal_sock() to request_sock.h
We will support arbitrary SYN Cookie with BPF.
If BPF prog validates ACK and kfunc allocates a reqsk, it will
be carried to TCP stack as skb->sk with req->syncookie 1.
In skb_steal_sock(), we need to check inet_reqsk(sk)->syncookie
to see if the reqsk is created by kfunc. However, inet_reqsk()
is not available in sock.h.
Let's move skb_steal_sock() to request_sock.h.
While at it, we refactor skb_steal_sock() so it returns early if
skb->sk is NULL to minimise the following patch.
