Subject: [PATCH v1 2/2] thermal: helpers: Rearrange thermal_cdev_set_cur_state()

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

Change the code layout in thermal_cdev_set_cur_state() so it returns
early on errors which is more consistent with what happens elsewhere.

No intentional functional impact.
