Disable absolute volume if the remote device rejects registration

Instead of trying to re-register for a rejected volume changed
notification, disable absolute volume. This prevents spinning if a
remote device continuously rejects all attempts to register. A volume
level of -2 will be used to represent that the volume notification was
rejected.
