reds: start QXL devices if VM is running

Browse Source 
Like char devices, QXL devices need to be explicily started.

For some historical reason, char devices are started when in running
state. See commi bf1d9007b. Reading that commit comments, there was a
plan to provide an API to stop/start devices invidually, but that never
happened. Whether that API would really be useful now, I wonder.

For now, just follow the char devices behaviour and start QXL devices
added when vm_running.
