virtio-serial: Apps should consume all data that guest sends out / Fix virtio api abuse
We cannot indicate to the guest how much data was consumed by an app for
out_bufs. So we just have to assume the apps will consume all the data
that are handed over to them.
Fix the virtio api abuse in control_out() and handle_output().
