evas/gl: Update texture when preload is cancelled.
Summary:
When preload is cancelled before finishing loading,
should reload the image data and update the texture during rendering object.
So, force texture to be updated on first drawing time.
(It should be guaranteed that preload image object is hidden before preload done.)
