[PATCH -next] PCI: xilinx-nwl: Add missing of_node_put() in nwl_pcie_init_irq_domain()

[Wei Yongjun]

From: Wei Yongjun <weiyongjun1 at huawei.com>

This node pointer is returned by of_get_next_child() with refcount
incremented in this function. of_node_put() on it before exitting
this function on error.

This is detected by Coccinelle semantic patch.
