sched/balancing: Remove reliance on 'enum cpu_idle_type' ordering when iterating [CPU_MAX_IDLE_TYPES] arrays in show_schedstat()
show_schedstat() output breaks and doesn't print all entries
if the ordering of the definitions in 'enum cpu_idle_type' is changed,
because show_schedstat() assumes that 'CPU_IDLE' is 0.
Fix it before we change the definition order & values.
[ mingo: Added changelog. ]
