ALSA: hda: intel-nhlt: Correct the handling of fmt_config flexible array

The struct nhlt_format's fmt_config is a flexible array, it must not be
used as normal array.
When moving to the next nhlt_fmt_cfg we need to take into account the data
behind the ->config.caps (indicated by ->config.size).

Fixes: a864e8f159b13 ("ALSA: hda: intel-nhlt: verify config type")
