vlan: should take into account needed_headroom
Commit c95b819ad7 (gre: Use needed_headroom)
made gre use needed_headroom instead of hard_header_len
This uncover a bug in vlan code.
We should make sure vlan devices take into account their
real_dev->needed_headroom or we risk a crash in ipgre_header(), because
we dont have enough room to push IP header in skb.
