[issue24038] Missing cleanup in list.sort() with key function

[Christian Heimes]

New submission from Christian Heimes:

One error path in list.sort() doesn't do proper cleanup. It neither sets an exception nor resets the internal pointers to its former values. In case of failed malloc() it leaves the list object in an invalid state.
