Merge branch 'net-sched-get-rid-of-cls_flower-egress_dev'

Jiri Pirko says:

====================
net: sched: get rid of cls_flower->egress_dev

Introduction of cls_flower->egress_dev was a workaround. Turned out
to be a bit ugly hack. So replace it with more generic and reusable
infrastructure.

This is a dependency of shared block introduction that will be send as
a follow-up patchsets group.
