Bjorn Helgaas 77a0dfcd8a PCI: Document reason for using pci_is_root_bus()
Some code assumes "bus->self == NULL" means the bus is a root bus.  This
adds a comment explaining why this is incorrect ("virtual" buses added for
SR-IOV have "bus->self == NULL" but are not root buses).

No functional change.
