[Why] The return value indicates whether the operation(disable/enable) succeeded or not. The existing logic reports wrong result even if the disablement was performed successfully. That will make succeeding reenablement abandoned as dc->idle_optimizations_allowed is always true.
[How] Correct the return value to reflect the real result of disablement.
