el9 dropped support for it, as the mainline kernel also did, see:
https://lore.kernel.org/lkml/20230307181940.868828-16-helgaas@kernel.org/

And git commit message saying:
```
pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.
