net: dont update dev->trans_start in 10GB drivers
Followup of commits 9d21493b4beb8f918ba248032fefa393074a5e2b
and 08baf561083bc27a953aa087dd8a664bb2b88e8e
(net: tx scalability works : trans_start)
(net: txq_trans_update() helper)
Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Multi queue drivers can
avoid one cache miss (on dev->trans_start) in their start_xmit()
handler.
Exceptions are NETIF_F_LLTX drivers (vxge & tehuti)
