[PATCH 1/4] ASoC: mediatek: common: return 0 from mtk_afe_fe_startup() on success

[phucduc . bui]

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

snd_pcm_hw_constraint_integer() may return 1, which is then returned
from mtk_afe_fe_startup(). ASoC only treats 0 as success when marking
the DAI as started, so .shutdown() can be skipped on rollback.

Return 0 explicitly on success.

Fixes: 283b612429a2 ("ASoC: mediatek: implement mediatek common structure")
Signed-off-by: bui duc phuc <phucduc.bui@xxxxxxxxx>
