The virtio device is removed when the remoteproc device is removed. The
driver should issue reset on the virtio device so the remote can do
corresponding cleanup.
Fixes: 7a186941626d ("remoteproc: remove the single rpmsg vdev limitation")

Shouldn't be the driver, and not the transport, the one that calls
virtio_reset_device()?
