As per PCI firmware specification r3.2 Downstream Port Containment
Related Enhancements ECN, sec 4.5.1, table 4-6, Error Disconnect
Recover (EDR) support allows OS to handle error recovery and
clearing Error Registers even in FF mode. So remove FF mode checks in
pci_cleanup_aer_uncorrect_error_status(), pci_aer_clear_fatal_status()
and pci_cleanup_aer_error_status_regs() functions.
