pwm: Remove unnecessary check before of_node_put()

Author: Markus Elfring <elfring@users.sourceforge.net>

The of_node_put() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
