Replace kfree_skb with dev_kfree_skb_any in vlan_insert_tag as vlan_insert_tag can be called from hard irq context (netpoll) and from other contexts. dev_kfree_skb_any is used as vlan_insert_tag only frees the skb if the skb can not be modified to insert a tag, in which case vlan_insert_tag drops the skb.
