svga: fix assert with PIPE_QUERY_OCCLUSION_PREDICATE for non-vgpu10

With this patch, when running in hardware version 11, we'll use
SVGA3D_QUERYTYPE_OCCLUSION query type for PIPE_QUERY_OCCLUSION_PREDICATE
and return TRUE if samples-passed count is greater than 0.

Fixes glretrace/solidworks2012_viewport running in hardware version 11.
