net/sched: sch_taprio: reset child qdiscs before freeing them
syzkaller shows that packets can still be dequeued while taprio_destroy()
is running. Let sch_taprio use the reset() function to cancel the advance
timer and drop all skbs from the child qdiscs.
Fixes: 5a781ccbd19e ("tc: Add support for configuring the taprio scheduler")
