The call to of_find_node_by_path returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.
Detected by coccinelle with the following warnings:
./arch/powerpc/platforms/powernv/opal.c:741:2-8: ERROR: missing of_node_put;
acquired a node pointer with refcount incremented on line 733, but without a
corresponding object release within this function.
