virtio_pci: remove struct virtio_pci_vq_info
We don't really need struct virtio_pci_vq_info, as most field in there
are redundant:
- the vq backpointer is not strictly neede to start with
- the entry in the vqs list is not needed - the generic virtqueue already
has list, we only need to check if it has a callback to get the same
semantics
- we can use a simple array to look up the MSI-X vec if needed.
- That simple array now also duoble serves to replace the per_vq_vectors
flag
