ASoC: reduce verbosity of error messages for sof-dai and sof-link
Recent changes result in multiple dmesg traces such as:

[ 14.410435] Audio Port: ASoC: error at snd_soc_link_startup on Audio
Port: 1

[ 14.410446] sst-mfld-platform sst-mfld-platform: ASoC: error at
snd_soc_dai_startup on media-cpu-dai: 1

These messages are not really errors, when dai and dai-link callbacks
return the value of e.g. snd_pcm_hw_constraint_single() the result is
"Positive if the value is changed, zero if it's not changed, or a
negative error code"

Add a simple test to skip the checks for positive returned values
