Enable all actions to have chance to consume incoming message. 

Some actions such as "DevicePowerStatusAction", "PowerStatusMonitorAction",
"Routing Contron Action" might wait for receiving <Report Power Status>
message, but the oldest aciton, which is normally PowerStatusMonitorAction,
can consume it.
This change enables all actions to have chance to touch incoming message.

Along with this, it fixes audio mute bug during volume control.
