[PATCH for-4.19 0/3] Backport of series: 'sched: A few small fixes for sch_cake' from 5.1

Hi Greg

This series contains backports for a couple of fixes to sch_cake that was just merged for 5.1. This series backports an earlier refactoring commit, which makes the fixes themselves apply cleanly from upstream.
