commit 198a62ddffa4a4ffaeb741f642b7b52f2d91ae9b upstream.
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.
