[PATCH 1/3] mm/slub: Only define kmalloc_large_node_hook() for NUMA systems

The function is only used when CONFIG_NUMA=y. Placing it in an #ifdef
block fixes the following warning when building with clang:

mm/slub.c:1246:20: error: unused function 'kmalloc_large_node_hook'
[-Werror,-Wunused-function]
