ASoC: es8311: Check regcache_sync() error in resume

The es8311_resume() function currently ignores the return value of
regcache_sync(). If syncing the cache fails, the function still returns
0, leaving the codec in a potentially incorrect state.

Check the return value and propagate it to the ASoC core to ensure
resume failures are properly handled.
