[PATCH RFC v4 01/21] PCI: Fix writing invalid BARs during pci_restore_state()

[Sergey Miroshnichenko]

If BAR movement has happened (due to PCIe hotplug) after pci_save_state(),
the saved addresses will become outdated. Restore them the most recently
calculated values, not the ones stored in an arbitrary moment.
