ASoC: ak4642: return cache sync errors from resume
ak4642_resume() restores cached registers during component resume but
discards the regcache_sync() result and returns success. A failed replay
can therefore leave the hardware register state stale without reaching
the component error reporting path.
Return the cache synchronization result. The ASoC component wrapper
reports a negative callback result and retains the established
best-effort resume state, so this adds observability without introducing
rollback or retry semantics.
The successful resume path is unchanged.
The issue was found by a tool we developed.
