MakeCondition: use sanitizeCompareOp

The sanitizeCompareOp function was added by the initial commit but never
ever used, thus the "unused" linter complains.

Looking at the code, this probably meant to be used from MakeCondition,
which already have a check for the comparison argument, but it only
checks for non-zero value.
