    batman-adv: Ignore invalid batadv_iv_gw during netlink send
    The function batadv_iv_gw_dump stops the processing loop when
    batadv_iv_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.
    Fixes: efb766af06e3 ("batman-adv: add B.A.T.M.A.N. IV bat_gw_dump implementations")
