A device_node reference obtained via of_find_node_by_path() requires
explicit calls to of_node_put() after it is no longer required to avoid
leaking the resource.
Add the missing calls to of_node_put(soc) in all execution paths when
'soc' is no longer required (one error path, and the success path).
