vti4: Don't count header length twice.
We currently count the size of LL_MAX_HEADER and struct iphdr twice for vti4 devices, this leads to a wrong device mtu. The size of LL_MAX_HEADER and struct iphdr is already counted in ip_tunnel_bind_dev(), so don't do it again in vti_tunnel_init(). Fixes: b9959fd3 ("vti: switch to new ip tunnel code") Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
