x86/PCI: Use pcibios_scan_root() instead of pci_scan_bus_on_node()
pcibios_scan_root() looks up the bus's NUMA node, then calls pci_scan_bus_on_node(). This uses pcibios_scan_root() directly and drops the node lookup in the callers. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
