Subject: [PATCH] iio: adc: dln2-adc: initialize local struct before using it

struct data is defined and declared locally. Initiliazation has to be done
manually, so let's add that.

This is more of a question actually! Did you have in mind that data is
not initialized here? If so, please drop this patch. This is just in case
you implicitely expected data to be zero.
