[PATCH 09/24] ASoC: atmel: atmel-pcm-pdc: Fix atmel_pcm_close() 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 atmel_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: 92dfa6198623 ("ASoC: atmel-pcm: split into two file")
