[PATCH 2/3] ASoC: SOF: sof-audio: keep prepare/unprepare widgets in sink path

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

From: Bard Liao <yung-chuan.liao@linux.intel.com>

The existing code return when a widget doesn't need to
prepare/unprepare. This will prevent widgets in the sink path from being
prepared/unprepared.
