In the other places in this function, guc->ads_map is being protected from access when it's not yet set. However the last check is actually about guc->ads_golden_ctxt_size been set before. These checks should always match as the size is initialized on the first call to guc_prep_golden_context(), but it's clearer if we have a single return and check for guc->ads_golden_ctxt_size. This is just a readability improvement, no change in behavior.
