clocksource: Resolve cpu hotplug dead lock with TSC unstable, fix crash
The watchdog timer is started after the watchdog clocksource
and at least one watched clocksource have been registered. The
clocksource work element watchdog_work is initialized just
before the clocksource timer is started. This is too late for
the clocksource_mark_unstable call from native_cpu_up. To fix
this use a static initializer for watchdog_work.
This resolves a boot crash reported by multiple people.
