ACPI: don't pass handle for fixed hardware notifications
Fixed hardware devices have no handles, so just pass an explicit NULL rather than something that looks like it might be meaningful. acpi_device_notify() doesn't need the handle anyway; the only reason it takes it as an argument is because the acpi_notify_handler typedef requires it.
