[PATCH 7/14 v2] powerpc/4xx/cpm: delete unneeded test before of_node_put

[Julia Lawall <julia.lawall@lip6.fr>]

From: Julia Lawall <Julia.Lawall@lip6.fr>

Simplify the error path to avoid calling of_node_put when it is not needed.

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

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