powerpc/fsl_rio: Fix refcount leak in fsl_rio_setup
[ Upstream commit fcee96924ba1596ca80a6770b2567ca546f9a482 ]
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
Fixes: abc3aeae3aaa ("fsl-rio: Add two ports and rapidio message units support")
