PCI: fix AER driver error information

Below patch fixes aer driver error information and enables aer driver
although CONFIG_ACPI=n.

As a matter of fact, the new patch is created from below 2 patches plus
a minor patch apply fuzz fixing. Because the second patch fixed a compilation
error introduced by the first patch, I merge them to facilitate bisect.
