pwm: Fix device reference leak

commit 0e1614ac84f1719d87bed577963bb8140d0c9ce8 upstream.

Make sure to drop the reference to the parent device taken by
class_find_device() after "unexporting" any children when deregistering
a PWM chip.

Fixes: 0733424c9ba9 ("pwm: Unexport children before chip removal")
