ASoC: mediatek: mt8195: add dai id check before accessing array

Browse source

Coverity shows "afe_priv->dai_priv[dai_id] evaluates to an address that
could be at negative offset of an array.". Add dai id check before
accessing the array element. This ensures that the offset of an array must
be a valid index.
