Miaoqian Lin c0ad5c7e68 PCI: microchip: Fix refcount leak in mc_pcie_init_irq_domains() ...

[ Upstream commit f030304fdeb87ec8f1b518c73703214aec6cc24a ]

of_get_next_child() returns a node pointer with refcount incremented, so we
should use of_node_put() on it when we don't need it anymore.

mc_pcie_init_irq_domains() only calls of_node_put() in the normal path,
missing it in some error paths.  Add missing of_node_put() to avoid
refcount leak.

Fixes: 6f15a9c9f9 ("PCI: microchip: Add Microchip PolarFire PCIe controller driver")
