batman-adv: invoke dev_get_by_index() outside of is_wifi_iface()
Upcoming changes need to perform other checks on the
incoming net_device struct.
To avoid performing dev_get_by_index() for each and every
check, it is better to move it outside of is_wifi_iface()
and search the netdev object once only.
