[PATCH] vlan: cleanup the usage of *vlan in vlan_dev_hard_header

[PATCH] vlan: cleanup the usage of *vlan in vlan_dev_hard_header

[Wang Sheng-Hui]

We can use vlan directly after we get the pointer at the beginning
     *vlan = vlan_dev_priv(dev)
and do not use vlan_dev_priv(dev) to access its fields afterwards.

We can use vlan directly after we get the pointer at the beginning
     *vlan = vlan_dev_priv(dev)
and do not use vlan_dev_priv(dev) to access its fields afterwords.
