Change the loop condition to avoid comparing unsigned value with 0.

This resulted in (useful) g++ warning and didn't make any sense in any case.

Check for the loop variable value being 0 at the end of the loop instead now.
If the old code was correct it shouldn't change its behaviour and if not, this
might fix a bug.
