drm/i915: Move all ring resets before setting the HWS page
In commit a51435a3137ad8ae75c288c39bd2d8b2696bae8f
Author: Naresh Kumar Kachhi <naresh.kumar.kachhi@intel.com>

drm/i915: disable rings before HW status page setup
we reordered stopping the rings to do so before we set the HWS register.
However, there is an extra workaround for g45 to reset the rings twice,
and for consistency we should apply that workaround before setting the
HWS to be sure that the rings are truly stopped.
