vhost driver in qemu didn't ack features, and this happens
to work because we don't really require any features. However,
it's better not to rely on this. This patch passes features to
vhost as guest acks them.

Anthony, here's a fixup patch to address an issue in vhost
patches. Incidentially, what's the status of the vhost patchset?
