[PATCH 19/24] ASoC: intel: atom: Fix .shutdown() being skipped on rollback

[phucduc . bui]

From: bui duc phuc <phucduc.bui@xxxxxxxxx>

snd_pcm_hw_constraint_integer() may return 1, which is then returned
from sst_media_open(). ASoC only marks the DAI as started when
.startup() returns 0, so .shutdown() can be skipped on rollback.

Return 0 explicitly on success.

Fixes: 4889a8a73f65 ("ASoC: intel: atom: Use __free(kfree) for stream pointer")
Fixes: 6cc0f4e63994 ("ASoC: Intel: mfld_pcm: move stream handling to dai_ops")
