virHostdevPreparePCIDevices: Separate out function body

In near future we will have a list of PCI devices we want to
detach (held in virPCIDeviceListPtr) but we don't have
virDomainHostdevDefPtr. That's okay because
virHostdevPreparePCIDevices() works with virPCIDeviceListPtr
mostly anyway. And in very few places where it needs
virDomainHostdevDefPtr are not interesting for our case.
