Fix following coccicheck warning:
./drivers/pci/controller/dwc/pcie-kirin.c:414:2-34: WARNING: Function
for_each_available_child_of_node should have of_node_put() before return.
Early exits from for_each_available_child_of_node should decrement the
node reference counter. Replace return by goto here and add a missing
of_node_put for parent.
