x86: NMI watchdog: Downgrade helper
A downgrade helper for the NMI watchdog to be used in all places where
the I/O APIC watchdog may have been requested, but the I/O APIC is found
not to be there or meant to be left disabled. This is so that the
reconfiguration is cosistent and defined in a single place only.
