Subject: [PATCH] virtio: console: Add a __send_control_msg() that can send
 messages without a valid port

We will introduce control messages that operate on the device as a whole
rather than just ports. Make send_control_msg() a wrapper around
__send_control_msg() which does not need a valid port.
