iio: adis_buffer: do not return ints in irq handlers

Browse Source 
[ Upstream commit d877539ad8 ]

On an IRQ handler we should not return normal error codes as 'irqreturn_t'
is expected.

Not necessarily stable material as the old check cannot fail, so it's a bug
we can not hit.

Fixes: ccd2b52f4a ("staging:iio: Add common ADIS library")
