ACPI PM: acpi_pm_device_sleep_state() cleanup
Get rid of a superfluous acpi_pm_device_sleep_state() parameter. The only legitimate value of that parameter must be derived from the first parameter, which is what all the callers already do. (However, this does not address the fact that ACPI still doesn't set up those flags.)
