PCI/PM: Clean up pci_set_low_power_state()

Make the following assorted non-essential changes in
pci_set_low_power_state():

 1. Drop two redundant checks from it (the caller takes care of these
    conditions).

 2. Change the log level of a messages printed by it to "debug",
    because it only indicates a programming mistake.
