Subject: [PATCH] PCI / PM: Clean up outdated comments in pci_target_state()

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Two comments in pci_target_state() are outdated, as the function
doesn't set the target power state for the device any more, only
finds one for it, so fix them accordingly.
