[issue37013] Fatal Python error in socket.if_indextoname()

[Zackery Spytz]

New submission from Zackery Spytz :

Python 3.8.0a4+ (heads/master:ef9d9b6312, May 22 2019, 08:35:25) 
[GCC 9.0.1 20190402 (experimental) [trunk revision 270074]] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> socket.if_indextoname(2**64 - 1)
Fatal Python error: a function returned NULL without setting an error
SystemError:  returned NULL without setting 
an error

Current thread 0x7f29d708d140 (most recent call first):
  File "", line 1 in 
Aborted (core dumped)

This is because socket.if_indextoname() does not use PyErr_Occurred() when 
checking PyLong_AsUnsignedLong() for failure.
