Without this initialization, gateways which actually announce up/down bandwidth of 0/0 could be added. If these nodes get purged later, the gw_node structure does not get removed since batadv_gw_node_delete() updates the gw_node with up/down bandwidth of 0/0, and the updating function then discards the change and does not free gw_node.
This results in leaking the gw_node structures, which references other structures: gw_node -> orig_node -> orig_node_ifinfo -> hardif. When removing the interface later, the open reference on the hardif may cause hangs with the infamous "unregister_netdevice: waiting for mesh1 to become free. Usage count = 1" message.
