As far as I can see it is not needed anymore since v6.0 following commit 
f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native")

Then the call has been removed from all drivers one by one, see for 
instance commit bc4fddc3b306 ("iavf: Remove redundant 
pci_enable_pcie_error_reporting()")
