iio: adc: ad9361: Fix ad9361_get_rx_gain() in split table mode

ad9361_gt() is returning the index from ad9361_adi_gt_info[]. Since this gain_table_info containts full table information too, the returned value will not be valid as an index for lna_table[][] and mixer_table[][]. Signed-off-by: Dragos Bogdan <[email protected]>
