Pass the shadow bo to qxl_io_create_primary() instead of expecting qxl_io_create_primary to check bo->shadow. Set is_primary flag on the shadow bo. Move the is_primary tracking into qxl_io_create_primary() and qxl_io_destroy_primary() functions.
That simplifies primary surface tracking and the workflow in qxl_primary_atomic_update().
