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.
