imx-drm: imx-drm-core: delete unneeded test before of_node_put 

Of_node_put supports NULL as its argument, so the initial test is not
necessary.

Suggested by Uwe Kleine-König.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/

)

// <smpl>

expression e;
@@

-if (e)
   of_node_put(e);
// </smpl>
