batman-adv: Fix check of retrieved orig_gw in batadv_v_gw_is_eligible
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. Fixes: 50164d8f500f ("batman-adv: B.A.T.M.A.N. V - implement GW selection logic") Signed-off-by: Sven Eckelmann <sven.eckelmann@openmesh.com> Acked-by: Antonio Quartulli <a@unstable.cc> Signed-off-by: Simon Wunderlich <sw@simonwunderlich.de>
