Change the tcp_probe tracepoint to accept a const struct sk_buff
parameter instead of a non-const one. This improves type safety and
better reflects that the skb is not modified within the tracepoint
implementation.

Sending this for net-next to avoid bringing this to stable tree, which
would make backport harder for not a big benefit.
