SLUB Debug: fix check for super sized slabs (>512k 64bit, >256k 32bit)
The check for super sized slabs where we can no longer move the free pointer behind the object for debugging purposes etc is accessing a field that is not setup yet. We must use objsize here since the size of the slab has not been determined yet. The effect of this is that a global slab shrink via "slabinfo -s" will show errors about offsets being wrong if booted with slub_debug. Potentially there are other troubles with huge slabs under slub_debug because the calculated free pointer offset is truncated.
