Davide Caratti 44d4775ca5 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: 5a781ccbd1 ("tc: Add support for configuring the taprio scheduler")
