vlan: enable multiqueue xmits
vlan_dev_hard_start_xmit() & vlan_dev_hwaccel_hard_start_xmit()
select txqueue number 0, instead of using index provided by
skb_get_queue_mapping().
This is not correct after commit 2e59af3dcbdf11635c03f
[vlan: multiqueue vlan device] because
txq->tx_packets & txq->tx_bytes changes are performed on
a single location, and not the right locking.
Fix is to take the appropriate struct netdev_queue pointer
