staging: iio: adc: fix error return code in ad7606_par_probe()
platform_get_irq() returns an error code, but the ad7606_par driver
ignores it and always returns -ENODEV. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.
Print and propagate the return value of platform_get_irq on failure.
This issue was detected with the help of Coccinelle.
