vlan: cleanup the usage of vlan_dev_priv(dev)
This patch cleanup 2 points for the usage of vlan_dev_priv(dev): * In vlan_dev.c/vlan_dev_hard_header, we should use the var *vlan directly after grabing the pointer at the beginning with *vlan = vlan_dev_priv(dev); when we need to access the fields of *vlan. * In vlan.c/register_vlan_device, add the var *vlan pointer struct vlan_dev_priv *vlan; to cleanup the code to access the fields of vlan_dev_priv(new_dev).
