net: Fix potential wrong skb->protocol in skb_vlan_untag() [ Upstream commit 55eff0eb7460c3d50716ed9eccf22257b046ca92 ] We may access the two bytes after vlan_hdr in vlan_set_encap_proto(). So we should pull VLAN_HLEN + sizeof(unsigned short) in skb_vlan_untag() or we may access the wrong data. Fixes: 0d5501c1c828 ("net: Always untag vlan-tagged traffic on input.")
