vlan: fix convertion to net_device_ops
commit 656299f706e52e0409733d704c2761f1b12d6954
(vlan: convert to net_device_ops) added a net_device_ops
with a NULL ndo_start_xmit field.
This gives a crash in dev_hard_start_xmit()
Fix it using two net_device_ops structures, one for hwaccel vlan,
one for non hwaccel vlan.
