You're not loading a node there, you're loading an entity of type entity_synclist. Its bundle key might be type, but it depends on what's defined in the module's implementation of hook_entity_info().
To be sure, you can get that information from the entity definition and use it to get the bundle like so:
$info = entity_get_info('entity_synclist'); $bundle_key = $info['entity keys']['bundle']; $synclist = entity_load_single('entity_synclist', $qid); $bundle = $synclist->{$bundle_key};
