pkt_sched: Fix tx queue selection in tc_modify_qdisc
After the recent mq change there is the new select_queue qdisc class method used in tc_modify_qdisc, but it works OK only for direct child qdiscs of mq qdisc. Grandchildren always get the first tx queue, which would give wrong qdisc_root etc. results (e.g. for sch_htb as child of sch_prio). This patch fixes it by using parent's dev_queue for such grandchildren qdiscs. The select_queue method's return type is changed BTW.
