ASoC: codecs: cs4349: Propagate regcache_sync() errors

Browse Source 
regcache_sync() can fail while replaying cached register state during
runtime resume. cs4349_runtime_resume() currently ignores that failure
and returns success.

Propagate the error, restore cache-only/dirty state, and hold reset low
again on sync failure.
