netdevice: add helper to update trans_start
trans_start exists twice:
- as member of net_device (legacy)
- as member of netdev_queue
In order to get rid of the legacy case, add a helper for the
dev->trans_update (this patch), then convert spots that do
dev->trans_start = jiffies
to use this helper (next patch).
This would then allow us to change the helper so that it updates the
trans_stamp of netdev queue 0 instead.
