sched/debug: Print out idle balance values even on !CONFIG_SCHEDSTATS kernels
The max_idle_balance_cost and avg_idle values which are tracked and ar used to capture short idle incidents, are not associated with schedstats, however the information of these two values isn't printed out on !CONFIG_SCHEDSTATS kernels.
Fix this by moving the value printout out of the CONFIG_SCHEDSTATS section.
