[PATCH] PM: Devfreq: fix userspace governor frequency bug

[Xiaoguang Chen <chenxg@marvell.com>]

The frequency set by userspace governor may not the
same as the final frequency. If this condition happens,
then "cat set_freq" will return a wrong value which is
inconsistant with the real frequency.

This patch updates data->user_frequency after calling
of update_devfreq. use devfreq->revious_freq as the
final user_frequency.
