iio: adc: ad_sigma_delta: fix irq_flags on irq request

With commit 7b0c9f8 ("iio: adc: ad_sigma_delta: Add optional irq
selection"), we can get the irq line from struct ad_sigma_delta_info
instead of the spi device. However, in devm_ad_sd_probe_trigger(), when
getting the irq_flags with irq_get_trigger_type() we are still using
the spi device irq instead of the one used for devm_request_irq().
