regulator: wm831x-dcdc: Fix the logic to choose best current limit setting
Current code in wm831x_buckv_set_current_limit actually set the current limit setting greater than specified range. Fix the logic in wm831x_buckv_set_current_limit to choose the smallest current limit setting falls within the specified range.
