PCI/PM: Clear state_saved during suspend
commit 82fee4d67ab86d6fe5eb0f9a9e988ca9d654d765 upstream.
This patch clears pci_dev->state_saved at the beginning of suspending.
PCI config state may be saved long before that. Some drivers call
pci_save_state() from the ->probe() callback to get snapshot of sane
configuration space to use in the ->slot_reset() callback.
