batman-adv: Fix check of retrieved orig_gw in batadv_v_gw_is_eligible

Browse Source 
The batadv_v_gw_is_eligible function already assumes that orig_node is not
NULL. But batadv_gw_node_get may have failed to find the originator. It
must therefore be checked whether the batadv_gw_node_get failed and not
whether orig_node is NULL to detect this error.
