virtio: check if avail ring is configured
If the connection to the vhost-user front end is closed during transfers
virtio rings are deconfigured and not available anymore, but we can
try to access them to process queued data. This can trigger a SIGSEG as
we try to access unavailable memory.
To fix that check vq->vring.avail is sane before accessing the vring
