inet: Turn ->remember_stamp into ->get_peer in connection AF ops.

Browse Source 
Then we can make a completely generic tcp_remember_stamp()
that uses ->get_peer() as a helper, minimizing the AF specific
code and minimizing the eventual code duplication when we implement
the ipv6 side of TW recycling.
