Merge branch 'net-sched-block-callbacks-follow-up'

Jiri Pirko says:

====================
net: sched: block callbacks follow-up

This patchset does a bit of cleanup of leftovers after block callbacks
patchset. The main part is patch 2, which restores the original handling
of tc offload feature flag.

---
v1->v2:
- rebased on top of current net-next (bnxt changes)
