python/sepolicy: use variables which exist in the gui.py

Some function used variables which were not defined when populating
self.cur_dict with an operation. Fix this, even though the old values do
not seem to be used.

This issue has been found using flake8. This Python linter reported:

    python/sepolicy/sepolicy/gui.py:2020:101: F821 undefined name 'oldsetype'
    python/sepolicy/sepolicy/gui.py:2020:122: F821 undefined name 'oldmls'
