virtio-pci: read the right virtio_pci_notify_cap field
Looks like a copy-paste bug. The value is used as an optimization and a wrong value probably isn't causing any serious damage. Found when porting this code to Windows. Signed-off-by: Ladi Prosek <lprosek@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
