Currently, get_vq_state() is used only to pass the available index value

For now, define VQ_STATE_NOT_READY. In the future it will be extended to
include other infomration.
Modify current vdpa driver to update this field.

What's the difference between this and get_vq_ready()?
Thanks
There is no difference. It is just a way to communicate a problem to
with the state of the VQ back to the caller. This is not available now.
I think an asynchronous is preferred but that is not available
currently.
I still don't see the reason, maybe you can give me an example?
Thanks
