rpmsg: virtio: Fix the unregistration of the device rpmsg_ctrl
Unregister the rpmsg_ctrl device instead of just freeing the
the virtio_rpmsg_channel structure.
This will properly unregister the device and call
virtio_rpmsg_release_device() that frees the structure.
Fixes: c486682ae1e2 ("rpmsg: virtio: Register the rpmsg_char device")
