PCI PM: Fix handling of devices without drivers

Suspend to RAM is reported to break on some machines as a result of
attempting to put one of driverless PCI devices into a low power

devices during suspend.

Fix up pci_pm_poweroff() after a previous incomplete fix for the same
thing during hibernation.

This patch is reported to fix the regression from 2.6.28 tracked as
