[PATCH 3/4] ASoC: SOF: intel: Use the generic helper to get the reply

[Daniel Baluta]

From: Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx>

Make use of the generic snd_sof_ipc_process_reply() from the core instead
the local implementation.
snd_sof_ipc_process_reply() handles the reply retrieving and the ipc reply
