Merge branch 'qdisc-destroy'

Vlad Buslov says:

====================
Fix Qdisc destroy issues caused by adding fine-grained locking to filter API

TC filter API unlocking introduced several new fine-grained locks. The
change caused sleeping-while-atomic BUGs in several Qdiscs that call cls
APIs which need to obtain new mutex while holding sch tree spinlock. This
series fixes affected Qdiscs by ensuring that cls API that became sleeping
is only called outside of sch tree lock critical section.
