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().
