net: axienet: delete unneeded test before of_node_put
Author: Julia Lawall <Julia.Lawall@lip6.fr>
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/)
//
@@
expression e;
@@
-if (e)
of_node_put(e);
