treemanifest: disable readdelta optimization When tree manifests are stored with one revlog per directory and loaded lazily, it's unclear how much readdelta will help. If only a few files change, then only a small part of the full manifest will be loaded, and the delta chains should also be shorter for tree manifests. Therefore, let's disable readdelta for tree manifests for now.
