Of_node_put supports NULL as its argument, so the initial test is not
necessary. Furthermore, native_mode cannot be NULL at this point.
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>
