RenderBase: Force a pipeline flush when drawing the XFB to the host

Browse Source 
Since we use the common pipelines here and draw vertices if a batch is
currently being built by the vertex loader, we end up trampling over its
pointer, as we share the buffer with the loader, and it has not been
unmapped yet. Force a pipeline flush to avoid this.
