The sequences are missing a call to snd_soc_dai_set_dma_data() when
the stream is cleared, as well as a release of the stream, and tests
to avoid pointer dereferences.

This fixes an underflow issue in a corner case with two streams paused
before a suspend-resume cycle. After resume, the pause_release of the
last stream causes an underflow due to an invalid sequence.

This problem probably existed since the beginning and is only see with
prototypes of a 'deep-buffer' capability, which depends on additional
ASoC fixes, so there's is no Fixes: tag and no real requirement to
backport this patch.
