Subject: [PATCH 7/7] batman-adv: fix vlan header access

When batadv_get_vid() is invoked in interface_rx() the
batman-adv header has already been removed, therefore
the header_len argument has to be 0.

Introduced by c018ad3de61a1dc4194879a53e5559e094aa7b1a
("batman-adv: add the VLAN ID attribute to the TT entry")
