iio: sca3000: Fix missing return in switch

Browse Source 
commit c5b974bee9d2ceae4c441ae5a01e498c2674e100 upstream.

The IIO_CHAN_INFO_LOW_PASS_FILTER_3DB_FREQUENCY case is missing a
return and will fall through to the default case and errorenously
return -EINVAL.

Fix this by adding in missing *return ret*.
