pkt_sched: sch_drr: fix drr_dequeue loop()
Jarek Poplawski points out:
If all child qdiscs of sch_drr are non-work-conserving (e.g. sch_tbf)
drr_dequeue() will busy-loop waiting for skbs instead of leaving the
job for a watchdog. Checking for list_empty() in each loop isn't
necessary either, because this can never be true except the first time.
Using non-work-conserving qdiscs as children of DRR makes no sense,
simply bail out in that case.
