cdx: call of_node_put() on error path
[ Upstream commit 87736ae12e1427bb2e6fd11f37b2ff76ed69aa0f ]
Add a missing call to of_node_put(np) on error.
There was a second error path where "np" was NULL, but that situation is
impossible. The for_each_compatible_node() loop iterator is always
non-NULL. Just deleted that error path.
