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.
