sched: Do not reduce perceived CPU capacity while idle

CPUs that are idle are excellent candidates for latency sensitive or high-performance tasks. Decrementing their capacity while they are idle will result in these CPUs being chosen less, and they will prefer to schedule smaller tasks instead of large ones. Disable this.
