Vladimir Oltean c862033595 net: dsa: tag_8021q: only call skb_push/skb_pull around __skb_vlan_pop 
__skb_vlan_pop() needs skb->data to point at the mac_header, while
skb_vlan_tag_present() and skb_vlan_tag_get() don't, because they don't
look at skb->data at all.

So we can avoid uselessly moving around skb->data for the case where the
VLAN tag was offloaded by the DSA master.
