PM / devfreq: Fix wrong trans_stat of passive devfreq device
commit 30582c25a4b4e0a5e456a309fde79b845e9473b2 upstream.
Until now, the trans_stat information of passive devfreq is not updated.
This patch updates the trans_stat information after setting the target
frequency of passive devfreq device.
