Subject[PATCH] sched/debug: fix idle balance factors aren't printed out if w/o CONFIG_SCHEDSTATS
Date
From: Wanpeng Li <wanpeng.li@hotmail.com>

max_idle_balance_cost and avg_idle which used to capture short idle
are not associated with schedstats, however, the information of these
two factors are't printed out if w/o CONFIG_SCHEDSTATS.

This patch fix it by moving max_idle_balance_cost and avg_idle print
out of CONFIG_SCHEDSTATS.
