sched/debug: Fix sd->*_idx limit range avoiding overflow
commit fd9b86d37a600488dbd80fe60cca46b822bff1cd upstream.
Commit 201c373e8e ("sched/debug: Limit sd->*_idx range on
sysctl") was an incomplete bug fix.
This patch fixes sd->*_idx limit range to [0 ~ CPU_LOAD_IDX_MAX-1]
avoiding array overflow caused by setting sd->*_idx to CPU_LOAD_IDX_MAX
on sysctl.
