ASoC: qcom: q6apm-lpass-dai: unprepare stream if its already prepared

Browse Source 
[ Upstream commit c2ac3aec474da0455df79c4a182f19687bc98d1d ]

prepare callback can be called multiple times, so unprepare the stream
if its already prepared.

Without this DSP is not happy to setting the params on a already
prepared graph.
