ASoC: codecs: rt1318-sdw: Propagate regcache_sync() errors

Browse Source 
regcache_sync() can fail while replaying cached register state after the
SoundWire slave has reinitialized. rt1318_dev_resume() currently ignores
that failure and returns success.

Propagate the error and restore cache-only/dirty state on failure.
