devfreq: Account only powered time in trans_stat
This patch modifies devfreq to account only the time a device is
powered in trans_stat. In addition, this patch also fixes a race
in trans_stat maintenance in cases where the node is readed at
the same time the transition table is being updated by frequency
re-estimation.
