pkt_sched: sch_multiq: Change errno on non-multiqueue devices use.

Current "RTNETLINK answers: Invalid argument" warning, while trying to
add multiq qdisc to non-multiqueue device, isn't very helpful and some
of these devs can be changed btw., so let's use a better errno.

With feedback from Stephen Hemminger <shemminger@vyatta.com>
