iio: light: vcnl4035: Propagate regcache_sync() errors

Browse Source 
vcnl4035_runtime_suspend() marks the regmap cache dirty before runtime
suspend. vcnl4035_runtime_resume() then syncs the cache before re-
enabling ALS, but currently ignores a regcache_sync() failure and can
still report resume success.

Return the regcache_sync() error so the PM core sees the failed register
restore.
