PCI: do not call pci_set_power_state with PCI_D3cold

PCI subsystem has not been ready for D3cold support yet. So PCI_D3cold should not be used as parameter for pci_set_power_state. This patch is needed for upcoming PCI_D3cold support. This patch has no functionality change, because pci_set_power_state will bound the parameter to PCI_D3hot too.
