Update changelog to make it clearer: The SLAB_MEM_SPREAD flag used to be implemented in SLAB, which was removed as of v6.8-rc1, so it became a dead flag. And the series[1] went on to mark it obsolete to avoid confusion for users. Here we can just remove all its users, which has no functional change.
