Rafael J. Wysocki 212967c69a ACPI / PM: Check device state before refcounting power resources 
Commit 3e384ee6c6 (ACPI / PM: Fix
reference counting of power resources) introduced a regression by
causing fan power resources to be turned on and reference counted
unnecessarily during resume, so on some boxes fans are always on
after resume.

Fix the problem by checking if the current device state is different
from the new state before reference counting and turning on power
resources in acpi_power_transition().
