Since patch ("virtio-pci: introduce modern device module") got added it
is not possible to boot a defconfig kernel in qemu with a virtio pci
device.  Add CONFIG_VIRTIO_PCI_MODERN=y fragment makes the kernel able
to boot.

Michael, can you pick this up in the vhost tree that introduces the regression?

Hi:

Based on the discussion previously, the plan is to select 
VIRTIO_PCI_MODERN, and document the module that select it must depend on 
PCI.

I will post a patch soon.

Thanks
