`ga_getitem` can fail if `Py_GenericAlias` returns `NULL`

Bug report

This code is problematic: https://github.com/python/cpython/blob/dc03ce797ae8786a9711e6ee5dcaadde02c55864/Objects/genericaliasobject.c#L565-L569

Why? Py_GenericAlias can return NULL in different cases: https://github.com/python/cpython/blob/dc03ce797ae8786a9711e6ee5dcaadde02c55864/Objects/genericaliasobject.c#L995-L999

So, we need to check for NULL.
