The current devfreq_update_status() has the following bugs:
- If previous frequency doesn't have a valid level, it does an out of bounds
   access into the trans_table and causes memory corruption.
- When the new frequency doesn't have a valid level, the time spent in the
   new frequency is counted towards the next valid frequency switch instead of
   being ignored.
- The time spent on the previous frequency is added to the new frequency's
   stats instead of the previous frequency's stats.

This patch fixes all of this.

Merged.

It appears to be Greg's LTS material as well.

Thanks!
