PM / Sleep: Fix build warning in sysfs.c for CONFIG_PM_SLEEP unset
The power/async device sysfs attribute is only used if both CONFIG_PM_ADVANCED_DEBUG and CONFIG_PM_SLEEP are set, but the code implementing it doesn't depend on CONFIG_PM_SLEEP. As a result, a build warning appears if CONFIG_PM_ADVANCED_DEBUG is set and CONFIG_PM_SLEEP is not set. Fix it by adding a #ifdef CONFIG_PM_SLEEP around the code in question. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
