Fix report type when rendering instances under availability zone
Fix report type when rendering instances under availability zone

When navigating to Cloud -> Availability Zone -> Utilization ->
Instances running / Instances stopped, we were using general
VM report, which we normally use to render both instances and vms
(all in one view).

It's better fit to render view we use when we render cloud instances.
