[PATCH v2 4/4] ASoC: mediatek: mt8365: Handle constraint return value in FE startup

[phucduc.bui@gmail.com]

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

snd_pcm_hw_constraint_integer() may return 1, which is then returned
from mt8365_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: e1991d102bc2 ("ASoC: mediatek: mt8365: Add the AFE driver support")
