iio: exynos-adc: fix irqf_oneshot.cocci warnings 

Author: Valentin Rothberg <valentinrothberg@gmail.com>

Since commit 1c6c69525b40 ("genirq: Reject bogus threaded irq requests")
threaded IRQs without a primary handler need to be requested with
IRQF_ONESHOT, otherwise the request will fail.

So pass the IRQF_ONESHOT flag in this case.
