[PATCH v2 2/4] ASoC: mediatek: mt8188: Handle constraint return value in FE startup

[phucduc.bui@gmail.com]

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

snd_pcm_hw_constraint_minmax() may return 1, which is then returned
from mt8188_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: bf106bf09376 ("ASoC: mediatek: mt8188: add platform driver")
