We have to store the congestion control timestamp on the SKB before we
clone it, not after. Else we get no timestamping information at all.
tcp_transmit_skb() has been reworked so that we can do the timestamp
still in one spot, instead of at all the call sites.
Problem discovered, and initial fix, from Tom Young
