commit 3d8d53554405952993bb0279ef3ebebc51740074 upstream

This reverts:

  commit 201c373e ("sched/debug: Limit sd->*_idx range on sysctl")

Load indexes (sd->*_idx) are no longer needed without rq->cpu_load[].
The range check for load indexes can be removed as well. Get rid of it
before the rq->cpu_load[] since it uses CPU_LOAD_IDX_MAX.

At the same time, fix the following coding style issues detected by
scripts/checkpatch.pl:

  ERROR: space prohibited before that ','
  ERROR: space prohibited before that close parenthesis ')'
