ASoC: codecs: rt5682-sdw: Propagate regcache_sync() errors

rt5682_io_init() and rt5682_dev_resume() both leave cache-only mode
before replaying cached register state with regcache_sync(). Both paths
ignore the sync result, which can hide a failed hardware restore.

Propagate regcache_sync() failures from both paths. The first hardware
init path now has a dedicated sync-failure cleanup that restores cache
bypass, cache-only, and dirty-cache state before balancing the runtime
PM reference. The resume path restores both regmaps to cache-only mode
and marks the main cache dirty before returning the error.
