net: dont update dev->trans_start

Second round of drivers for Gb cards (and NIU one I forgot in the 10GB round)

Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Drivers can avoid one cache miss
(on dev->trans_start) in their start_xmit() handler.

Exceptions are NETIF_F_LLTX drivers
