sch_mqprio: Always set num_tc to 0 in mqprio_destroy()
All the cleanup code in mqprio_destroy() is currently conditional on priv->qdiscs being non-null, but that condition should only apply to the per-queue qdisc cleanup. We should always set the number of traffic classes back to 0 here. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
