qxl-wddm-dod: Fix for screen not shown after driver disabled

Browse Source 
https://bugzilla.redhat.com/show_bug.cgi?id=1411340
Do not set SupportNonVGA field for device rev.4 and higher.
Then the class driver will not call miniport's procedure
StopDeviceAndReleasePostDisplayOwnership upon PnP stop.
QXL device modes are not compatible with VGA ones; the
driver in this procedure returns display information related
to QXL mode which later used by BasicDisplay driver and causes
it to show the screen incorrectly or fail to show it at all.
