vDPA supports the possibility to use user VA in the iotlb messages.
So, let's add support for user VA in vringh to use it in the vDPA
simulators.

Oops, good catch!

Copy & past typos also present in the documentation of vringh_init_kern
and vringh_init_iotlb.

I will fix this patch and send a separate patch to fix the other two.

Thanks,
Stefano
