thermal: gov_step_wise: Adjust code logic to match comment
For the algorithm of choosing the next target state in step_wise governor, the code does the right thing but is implemented in a way different from what the comment describes. And this hurts the code readability. As the logic in the comment is simpler, adjust the code logic to align with the comment. No functional change.
