[PATCH 6.19 199/844] ASoC: sdw_utils: remove dai registered check

[Sasha Levin]

From: Bard Liao <yung-chuan.liao@xxxxxxxxxxxxxxx>

[ 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.
