[PATCH v1 1/2] thermal: gov_step_wise: Simplify get_target_state()

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

The step-wise governor's get_target_state() function contains redundant
braces, redundant parens and a redundant next_target local variable, so
get rid of all that stuff.

No intentional functional impact.
