of: Delete an unnecessary check before the function call « of_node_put »

Classé dans Coccinelle, Linux

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.
