[PATCH 6/8] ASoC: SOF: control: Do not handle control notification with component type

From: Peter Ujfalusi <peter.ujfalusi at linux.intel.com>

The component type is not used in firmware nor in the kernel currently and
it is not even clear how it should be handled.

Do not even try to handle it to avoid errors.
