[PATCH] vfio/pci: Fix instance_size of VFIO_PCI_BASE

[Zhenzhong Duan]

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.

Fixes: d4e392d0a99b ("vfio: add vfio-pci-base class")
