[PATCH 18/24] ASoC: imx-pcm-rpmsg: Fix imx_rpmsg_pcm_close() being skipped on rollback

[phucduc . bui]

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

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

Return 0 explicitly on success.

Fixes: 3c00eceb2a53 ("ASoC: imx-pcm-rpmsg: Add platform driver for audio base 
on rpmsg")
