ASoC: qdsp6: q6apm-dai: unprepare stream if its already prepared

Browse Source 
commit 6548c884a595391fab172faeae39e2b329b848f3 upstream.

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.
