score: Disable thread dispatching earlier

Disable thread dispatching earlier on secondary processors.  This ensures that
fatal error and per-CPU job handlers are called with thread dispatching
disabled.  On the boot processor, the thread dispatching is already disabled by
_Thread_Dispatch_initialization().
