Revert accidental isl changes in 308923

It seems I still had some incomplete changes in the tree when committing.
In general, we only import changes from isl upstream. In this case, the
changes were especially unfortunate, as they broke the error management
in isl_flow.c and consequently caused regressions.

Thanks to Michael Kruse for spotting this mistake.
