Peter Zijlstra e4c2fb0d57 sched: Disable (revert) SCHED_LOAD_SCALE increase
Alex reported that commit c8b281161d ("sched: Increase
SCHED_LOAD_SCALE resolution") caused a power usage regression
under light load as it increases the number of load-balance
operations and keeps idle cpus from staying idle.

Time has run out to find the root cause for this release so
disable the feature for v3.0 until we can figure out what
causes the problem.
