PCI/AER: Don't read upstream ports below fatal errors
The AER driver has never read the config space of an endpoint that reported a fatal error because the link to that device is considered unreliable. An ERR_FATAL from an upstream port almost certainly indicates an error on its upstream link, so we can't expect to reliably read its config space for the same reason.
