Why there's such limitation for the number of vDPA virtqueues? I thought the
software virtio doesn't have this limitation (power of two).
Right, the limitation comes from mlx5_vdpa. I will post a patch later to
remove that limitation.

I mean the check should not live here. Other vdpa vendor device/driver 
may not have this limitation.
