After r135620, Accelerated Compositing does not draw some pages, because r135620 changes the tree-traversal. Before r135620, we returned early if TextureMapperLayer can not gain TextureMapper from the root layer. However, after r135620, we run the tree-traversal even if TextureMapperLayer can not gain TextureMapper. This patch makes TextureMapperLayer return early like code before r135620.
