tcp: remove obsolete comment about TCP_SKB_CB(skb)->when in tcp_fragm…

…ent() The TCP_SKB_CB(skb)->when field no longer exists as of recent change 7faee5c ("tcp: remove TCP_SKB_CB(skb)->when"). And in any case, tcp_fragment() is called on already-transmitted packets from the __tcp_retransmit_skb() call site, so copying timestamps of any kind in this spot is quite sensible.
