[PATCH v3, part1 08/10] PCI, IOV: don't touch bus->is_added flag

[Jiang Liu <liuj97@gmail.com>]

The flag pci_bus->is_added is used to guard invoke of
pcibios_fixup_bus(pci_bus). And when virtfn_add_bus() is called,
pci_bus->is_added flag has already been set, so remove the redandunt
	bus->is_added = 1;
