: Fix tbf_reset

This patch fixes TBF purging an unused queue in tbf_reset instead of resetting q.qlen. I haven't checked the history, but it looks like this place was forgotten when making TBF classful.

Best regards,
Patrick

Yes, the bug was introduced when adding inner-qdisc attaching support to TBF.

Thanks for tracking this down Patrick, patch applied.
