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: 6e962bfe ("remoteproc: imx_rproc: add missing of_node_put")
Fixes: a0ff4aa6 ("remoteproc: imx_rproc: add a NXP/Freescale imx_rproc driver")
