virtio_pci: struct virtio_pci_common_cfg add queue_notify_data
Add queue_notify_data in struct virtio_pci_common_cfg, which comes from
here https://github.com/oasis-tcs/virtio-spec/issues/89
In order not to affect the API, add a dedicated structure struct
virtio_pci_modern_common_cfg to virtio_pci_modern.h.
Since I want to add queue_reset after queue_notify_data, I submitted
this patch first.
