Merge branch 'small-tc-taprio-improvements'

Vladimir Oltean says:

====================
Small tc-taprio improvements

This series contains:
- the proper protected variant of rcu_dereference() of admin and oper
  schedules for accesses from the slow path
- a removal of an extra function pointer indirection for
  qdisc->dequeue() and qdisc->peek()
- a removal of WARN_ON_ONCE() checks that can never trigger
- the addition of netlink extack messages to some qdisc->init() failures

These were split from an earlier patch set, hence the v2.
