ASoC: sdw_utils: remove dai registered check
[ Upstream commit 8d38c275f7ffe257d21bea224d4288eef183817d ]
Checking for a registered DAI for non-existing endpoints causes the
following error. The driver will always return -EPROBE_DEFER if the
codec driver doesn't register the DAI of the unexist endpoint.
