remoteproc: imx_rproc: Fix refcount leak in imx_rproc_addr_init
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not needed anymore.
This function has two paths missing of_node_put().
Fixes: 6e962bfe56b9 ("remoteproc: imx_rproc: add missing of_node_put")
Fixes: a0ff4aa6f010 ("remoteproc: imx_rproc: add a NXP/Freescale imx_rproc driver")
