Fix buffer usage printing in dlogutil

Without converting to unsigned long long, the calculation would overflow
when the buffer usage would get higher than around 42 MB. This doesn't
really happen, since the buffer capacity currently is not even close to
that value. However, there's no reason not to fix this.
