Subject: [PATCH 1/3] batman-adv: fix skb leak in batadv_dat_snoop_incoming_arp_reply()

From: Matthias Schiffer <mschiffer@...verse-factory.net>

The callers of batadv_dat_snoop_incoming_arp_reply() assume the skb has been
freed when it returns true; fix this by calling kfree_skb before returning as
it is done in batadv_dat_snoop_incoming_arp_request().
