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.
