When UVD is in VM mode, there is not uvd handle exchanged,
uvd.handles are always 0. So vcpu_bo always need save,
Otherwise amdgpu driver will fail during suspend/resume.

Would be nice to completely skip the check on Polaris and newer. In
other words:
If (adev->asic_type < CHIP_POLARIS10) {
for (i= 0;.....
if (i== adev->uvd.max_handles)
return 0;
}
But that is purely nice to have, both patches are Reviewed-by: Christian
