The label oops is used in CONFIG_DEBUG_VM ifdef block and is defined
outside ifdef CONFIG_DEBUG_VM block. This results in the following
build warning when built with CONFIG_DEBUG_VM disabled. Fix to move
label oops definition to inside a CONFIG_DEBUG_VM block.

mm/slab_common.c: In function ?kmem_cache_create?:
mm/slab_common.c:101:1: warning: label ?oops? defined but not used
[-Wunused-label]

I merged this as an obvious and safe fix for current merge window. We
need to clean this up properly for v3.7.

-Wunused-label is overridden in gcc for a label that is conditionally 
referenced by using __maybe_unused in the kernel.  I'm not sure what's so 
obscure about

out: __maybe_unused

Are label attributes really that obsecure?
