[PATCH v3 1/4] PCI: Keep AER status in pci_restore_state()

[Kai-Heng Feng]

When AER is using the same IRQ as PME, AER interrupt is treated as a
wakeup event and it can disrupt system suspend process.

If that happens, the system will report it's woken up by PME IRQ without
indicating any AER error since AER status is cleared on resume.

So keep the AER status so users can know the system is woken up by AER
instead of PME.
