No, it doesn't seem to work that way. Those callback seems to
be for bus reported errors, not device reported errors.

On boot up it clears errors because power on seems to leave a bogus
error report.

When error is detected, it gets an IRQ and than has to decode it as PCI
error.

Earlier versions of the driver (pre AER) were doing the same thing but
with only minimal handling of errors. Now at least it uses common code.
