batman-adv: Increase hard_iface refcnt for ptype
The hard_iface is referenced in the packet_type for batman-adv. Increase the refcounter of the hard_interface for it to have an explicit reference for it in case this functionality gets refactorted and the currently used implicit reference for it will be removed.
