In all 3 drivers there is a case where the driver knows the
bo is in SYSTEM so don't call the api that checks that.

In the long term I completely want to get rid of this nonsense because 
it means that we call back into TTM which then calls us again.

But for now the patch is Reviewed-by: Christian König
