[PATCH 17/24] ASoC: codecs: wm8782: Ensure the DAI is marked as started on success

[phucduc . bui]

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

snd_pcm_hw_constraint_minmax() may return 1, which is then returned
from wm8782_dai_startup(). ASoC only marks the DAI as started when
.startup() returns 0.

This currently has no functional impact, as wm8782_dai_ops has no
.shutdown() callback. Still, return 0 explicitly on success to
match what ASoC expects and ensure the DAI is correctly marked as
started.
