[issue3662] _fileio._FileIO segfaults

Daniel, thanks for running the fuzzer!  It would be great if you could
keep running it and find any more problems before releasing 2.6 and 3.0.

I agree with Benjamin and Amaury.  PyArg_ParseTupleAndKeywords()
shouldn't update the pointer if it failed.  Given the test, it's
unlikely for this to create a problem in the future.  Either as a crash
or as a memory leak.

Committed revision 66018. (2.6)
Committed revision 66019. (3.0)
