Azat Khuzhin reported "high loadavg in linux-3.6"

After checking for upstream's code, I found Peter's patch
(Commit id:5167e8d5417bf5c322a703d2927daec727ea40dd) not be
fully applied, missing the call for calc_load_exit_idle.
After that idle exit in sampling window will always be calculated
 to non-idle, and the load will be higher than normal.

This patch add the missing call for calc_load_exit_idle.
