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.")
