Markus Elfring 3694bfbdb3 dwc_eth_qos: Delete an unnecessary check before the function call "of_node_put" 
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.
