batman-adv: fix memory leak in in batadv_dat_put_dhcp
batadv_dat_put_dhcp is creating a new ARP packet via
batadv_dat_arp_create_reply and tries to forward it via
batadv_dat_send_data to different peers in the DHT. The original skb is not
consumed by batadv_dat_send_data and thus has to be consumed by the caller.
Fixes: b61ec31c8575 ("batman-adv: Snoop DHCPACKs for DAT")
