hwmon: (twl4030-madc-hwmon) Initialize uninitialized structure elements
commit 73d7c119255615a26070f9d6cdb722a166a29015 upstream.
twl4030_madc_conversion uses do_avg and type structure elements of
twl4030_madc_request. Initialize structure to avoid random operation.
Fix for: Coverity CID 200794 Uninitialized scalar variable.
