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.)
