cell: handle NULL cso vertex_elements state object on bind
drivers need to handle NULL cso vertex elements (and others) objects. It is possible the cso code saves/restores NULL objects (if no normal cso object was bound before this was invoked). This led to segfaults (for example demos/cubemap) for apps which were using things like creating mipmaps before drawing anything.
