[PATCH v4 01/16] ASoC: amd: acp: fix missing cleanup on devm_kasprintf() failure in mc_probe()

[Vijendar Mukunda]

On devm_kasprintf() failure for the cfg-amp components string,
mc_probe() returned -ENOMEM directly without calling
asoc_sdw_mc_dailink_exit_loop(), leaving device references acquired
during sof_card_dai_links_create() unreleased.

Call asoc_sdw_mc_dailink_exit_loop() before returning -ENOMEM to
release those references, consistent with the cleanup already done
in the devm_snd_soc_register_card() failure path.

Fixes: cb8ea62e6402 ("ASoC: amd/sdw_utils: add sof based soundwire generic machine driver")
