This should instead be

kvm-objs-$(CONFIG_PCI) += pci.o

I think this makes sense as we aren't about to do PCI passthrough
support anyway if the host kernel doesn't support PCI (no vfio-pci,
etc). This will quiet the kernel test robot complaints about
CONFIG_PCI_NR_FUNCTIONS seen on the next patch in this series.
