The GEM object free handler frees memory allocated by the driver using the pointer to the drm_gem_object instead of the pointer to the omap_gem_object that embeds it. This doesn't cause any issue in practice as the drm_gem_object is the first field of omap_gem_object, but would cause memory corruption if the structure layout changes. Fix it.
