tcp: refresh skb timestamp at retransmit time
[ Upstream commit 10a81980fc47e64ffac26a073139813d3f697b64 ]
In the very unlikely case __tcp_retransmit_skb() can not use the cloning
done in tcp_transmit_skb(), we need to refresh skb_mstamp before doing
the copy and transmit, otherwise TCP TS val will be an exact copy of
original transmit.
Fixes: 7faee5c0d514 ("tcp: remove TCP_SKB_CB(skb)->when")
