x86, NMI watchdog: disable NMIs on LVT0 in case NMI watchdog is not working

Impact: change NMI watchdog detection and disabling sequence

Currently, if the NMI watchdog fails using IOAPIC method, it'll only disable
interrupts on 8259 if the timer is passing thru it. This patch disables
NMI delivery on LINT0 if the NMI watchdog initial test fails, just for safety.
