pkt_sched: fq: change classification of control packets
Initial sch_fq implementation copied code from pfifo_fast to classify a packet as a high prio packet. This clashes with setups using PRIO with say 7 bands, as one of the band could be incorrectly (mis)classified by FQ. Packets would be queued in the 'internal' queue, and no pacing ever happen for this special queue.
