iio: adc: ade9000: fix wrong return type in streaming push

The else branch of ade9000_iio_push_streaming() incorrectly returns
IRQ_HANDLED on regmap_write failure. This function returns int (0 on
success, negative errno on failure), so IRQ_HANDLED (1) would be
misinterpreted as a non-error by callers.

Return ret instead, consistent with every other error path in the
function.
