ASoC: amd: acp-sdw-legacy: check CPU DAI name before logging

devm_kasprintf() can fail and return NULL. The legacy AMD SoundWire
machine driver logs cpus->dai_name before checking the allocation result.

Move the debug print after the NULL check, matching the ordering used by
the SOF AMD SoundWire path after commit 5726b68473f7 ("ASoC: amd/sdw_utils:
avoid NULL deref when devm_kasprintf() fails").

Fixes: 2981d9b0789c ("ASoC: amd: acp: add soundwire machine driver for legacy stack")
