[PATCH] ASoC: codecs: rt722-sdca-sdw: Propagate regcache_sync() errors

[Pengpeng Hou]

rt722_sdca_dev_resume() waits for SoundWire initialization, leaves
cache-only mode, and replays cached register state. It currently ignores
regcache_sync() failures and returns success.

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