batman-adv: fix batman-adv header overhead calculation

Batman-adv prepends a full ethernet header in addition to its own
header. This has to be reflected in the MTU calculation, especially
since the value is used to set dev->hard_header_len.

Introduced by 411d6ed93a
("batman-adv: consider network coding overhead when calculating required mtu")
