ASoC: amd/sdw_utils: avoid NULL deref when devm_kasprintf() fails

Browse source

[ Upstream commit 5726b68473 ]

devm_kasprintf() may return NULL on memory allocation failure,
but the debug message prints cpus->dai_name before checking it.
Move the dev_dbg() call after the NULL check to prevent potential
NULL pointer dereference.
