ASoC: codecs: rt721-sdca-sdw: Propagate regcache_sync() errors

rt721_sdca_dev_resume() clears cache-only mode for both regmaps and
replays cached register state. Both regcache_sync() calls currently
ignore their return values.

Check both sync operations, return the first error, and restore both
regmaps to cache-only/dirty state on failure.
