You can do so by deleting the root qdisc for each device.  Thus, supposing
some configuration similar to the following,

  qdisc cbq 1: dev eth1 rate 100Mbit (bounded,isolated) prio no-transmit
  qdisc cbq 2: dev eth2 rate 100Mbit (bounded,isolated) prio no-transmit

you can delete the root qdisc from each device with this command:

  # tc qdisc del dev eth1 root
  # tc qdisc del dev eth2 root

Everything that depends on the root qdisc (which, IIRC, is indeed
everything) will be deleted when the root qdisc is deleted.
