Hmm, good point that changing this is going to potentially change the
order in which the volume/mute/... messages are going to be sent, and
delay them a bit. It will also cause less messages to be sent if the
user keeps calling spice_server_playback_set_volume() (for example).

I don't think the messages are going to be delayed for a long time
though, so this should not really cause an issue (ie we should be fine
making that change without trying to get the exact same message order as
before)
