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 Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Michael S.
