Subject: [PATCH -v6 3/4] PCI, PM, 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.
