batman-adv: Ignore invalid batadv_v_gw during netlink send
The function batadv_v_gw_dump stops the processing loop when
batadv_v_gw_dump_entry returns a non-0 return code. This should only
happen when the buffer is full. Otherwise, an empty message may be
returned by batadv_gw_dump. This empty message will then stop the netlink
dumping of gateway entries. At worst, not a single entry is returned to
userspace even when plenty of possible gateways exist.
