iio: light: rpr0521: Propagate regcache_sync() errors

Browse source

rpr0521_runtime_suspend() powers the device down and marks the regmap
cache dirty. rpr0521_runtime_resume() syncs the cache before restoring
enabled ALS/PXS channels, but currently ignores a regcache_sync()
failure and can still return success.

Return the regcache_sync() error so resume does not hide a failed
register restore.
