[PATCH] PCI: apple: Add of_node_put() before return

[Wan Jiabing]

Fix following coccicheck warning:
./drivers/pci/controller/pcie-apple.c:771:1-23: WARNING: Function
for_each_child_of_node should have of_node_put() before return

Early exits from for_each_child_of_node should decrement the
node reference counter.
