[PATCH v2 03/25] ASoC: amd: ps: Fix acp63_sdw_dma_close() being skipped on rollback

From: bui duc phuc <phucduc.bui at gmail.com>

snd_pcm_hw_constraint_integer() may return 1, which is then returned
from acp63_sdw_dma_open(). ASoC only marks the component as opened
when .open() returns 0, so .close() can be skipped on rollback.

Return 0 explicitly on success.
