I keep looking at this and thinking why? Why was it added and what is
it protecting. Looking at libvirt_virErrorFuncHandler it seems only
libvirt_virPythonErrorFuncCtxt gets the Py_XINCREF and that's based on
whether libvirt_virPythonErrorFuncHandler is NULL or not.
Just feels like something subtle is going on. Also it's a register
handler and we're decrementing something that never got incremented.
