device/pci_device: Do not break tree topology

Fix regression introduced with commit
   ad7674e device: Introduce pcidev_on_root() and friends

Function pci_scan_bus() breaks bus->children link
in the devicetree topology while scanning a bus.
While the scan is in progress, accessing PCI
devices with number higher than what is being probed
was not possible because new pcidev_on_root() relies
on having proper topology present at any time.
