PM / devfreq: Fix wrong trans_stat of passive devfreq device

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.

Fixes: 99613311 ("PM / devfreq: Add new passive governor")
