ASoC: SOF: pcm: Clear the susbstream pointer to NULL on close

Browse Source 
commit 46c7b901e2 upstream.

The spcm->stream[substream->stream].substream is set during open and was
left untouched. After the first PCM stream it will never be NULL and we
have code which checks for substream NULLity as indication if the stream is
active or not.
For the compressed cstream pointer the same has been done, this change will
correct the handling of PCM streams.

Fixes: 090349a9fe ("ASoC: SOF: Add support for compress API for stream data/offset")
