SLUB Debug: fix initial object debug state of NUMA bootstrap objects
The function we are calling to initialize object debug state during early NUMA bootstrap sets up an inactive object giving it the wrong redzone signature. The bootstrap nodes are active objects and should have active redzone signatures. Currently slab validation complains and reverts the object to active state.
