Subject: PCI: xilinx-nwl: Add missing of_node_put()

Git-commit: 342639d996f18bc0a4db2f42a84230c0a966dc94

Patch-mainline: v4.18-rc4

References: bsc#1109806

The call to of_get_next_child() returns a node pointer with

refcount incremented thus it must be explicitly decremented

here after the last usage.

Fixes: ab597d35ef11 ("PCI: xilinx-nwl: Add support for Xilinx NWL PCIe Host Controller")
