virtio-devices: vhost-user: Fix device reset

Browse Source 
There is no need to get the vring base when resetting the vhost-user
device. This was mostly ignored, but in some cases, it was causing some
actual errors.

A reset must simply be a combination of disabling the vrings along with
the reset of the owner.
