Subject: [PATCH 3/3] ASoC: soc_sdw_utils: drop bogus container_of() error handling

The dev_to_sdw_dev() helper uses container_of() to return the containing
soundwire device structure of its pointer argument and will never return
NULL.

Fixes: 4f8ef33dd44a ("ASoC: soc_sdw_utils: skip the endpoint that doesn't present")
