batman-adv: Fix rx packet/bytes stats on local ARP reply

Browse Source 
commit 36d4d68cd658d914ef73ac845705c4a89e7d9e2f upstream.

The stats are generated by batadv_interface_stats and must not be stored
directly in the net_device stats member variable. The batadv_priv
bat_counters information is assembled when ndo_get_stats is called. The
stats previously stored in net_device::stats is then overwritten.

The batman-adv counters must therefore be increased when an ARP packet is
answered locally via the distributed arp table.
