x86: touch_nmi_watchdog(): reset alert counters for supported nmi_watchdog modes only
The checking 'if nmi_watchdog > 0' (ie NMI_NONE) is quite fast but it has a side effect - it's taken even if nmi_watchdog = NMI_DISABLED. Nowadays nmi_watchdog is set up to NMI_NONE by default so this condition is properly taken most the time but we better show this explicitly.
