PCI: Clear saved_state after the state has been restored
Some PCI devices fail if their standard configuration registers are restored twice in a row. Prevent this from happening by making pci_restore_state() clear the saved_state flag of the device right after the device's standard configuration registers have been populated with the previously saved values. Simplify PCI PM callbacks by removing the direct clearing of state_saved from them, as it shouldn't be necessary any more (except in pci_pm_thaw(), where it has to be cleared, so that the values saved during the "freeze" phase of hibernation are not used later by mistake).
