Remove rework check for dependencies in RebaseSorter

The REWORK check that was added by me in Change 91703, is just to be
cautious. However, after some thoughts about this, I don't think it is
really necessary based on the following facts:

* The diff of the change (which based on some old ps of its parent
change) has been reviewed.
* If there was a major rework on the parent change, there will be a merge
conflict when the change is merged.
