drm/i915/gvt: Disable access to stolen memory as a guest

commit ddd09373628adcbdc3f7b9098d22328834f8d772 upstream.

Explicitly disable stolen memory when running as a guest in a virtual
machine, since the memory is not mediated between clients and reserved
entirely for the host. The actual size should be reported as zero, but
like every other quirk we want to tell the user what is happening.
