thermal: gov_step_wise: Clean up thermal_zone_trip_update()
Do some assorted cleanups in thermal_zone_trip_update():
* Compute the trend value upfront.
* Move old_target definition to the block where it is used.
* Adjust white space around diagnostic messages and locking.
* Use suitable field formatting in a message to avoid an explicit
cast to int.
