[PATCH] of: Delete an unnecessary check before the function call "of_node_put"

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 19 Jul 2016 22:42:22 +0200

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.
