vlan: fix network_header/mac_header adjustments
Lennert Buytenhek points out that the VLAN code incorrectly adjusts
skb->network_header to point in the middle of the VLAN header and
additionally tries to adjust skb->mac_header without checking for
validity.
The network_header should not be touched at all since we're only
adding headers in front of it, mac_header adjustments are not
necessary at all.
Based on patch by Lennert Buytenhek <buytenh@wantstofly.org>.
