SLUB: Fix CONFIG_SLUB_DEBUG use for CONFIG_NUMA

SLUB: Fix CONFIG_SLUB_DEBUG use for CONFIG_NUMA

[Christoph Lameter]

We currently cannot disable CONFIG_SLUB_DEBUG for CONFIG_NUMA. Now that 
embedded systems start to use NUMA we may need this.

Put an #ifdef around places where NUMA only code uses fields only valid
for CONFIG_SLUB_DEBUG.
