ASoC: soc-core.c: fixup snd_soc_of_get_dai_link_cpus()

commit 900dedd7 ("ASoC: Introduce snd_soc_of_get_dai_link_cpus")
adds new snd_soc_of_get_dai_link_cpus(), but it is using
"codec" everywhere. It is very strange, and is issue when error case.
It should call cpu instead of codec in error case.
This patch tidyup it.
