vfio/pci: Fix instance_size of VFIO_PCI_BASE

Browse Source 
Currently the final instance_size of VFIO_PCI_BASE is sizeof(PCIDevice).
It should be sizeof(VFIOPCIDevice), VFIO_PCI uses same structure as
base class VFIO_PCI_BASE, so no need to set its instance_size explicitly.

This isn't catastrophic only because VFIO_PCI_BASE is an abstract class.
