[PATCH -tip] x86: k8.h reference to node in node_to_k8_nb_misc for !CONFIG_K8_NB

[Jaswinder Singh Rajput <jaswinder@kernel.org>]

Add reference to node in node_to_k8_nb_misc for !CONFIG_K8_NB to make compiler happy.

So fixes compiler warnings:
  arch/x86/kernel/cpu/intel_cacheinfo.c: In function ‘show_cache_disable’:
  arch/x86/kernel/cpu/intel_cacheinfo.c:712: warning: unused variable ‘node’
  arch/x86/kernel/cpu/intel_cacheinfo.c: In function ‘store_cache_disable’:
  arch/x86/kernel/cpu/intel_cacheinfo.c:739: warning: unused variable ‘node’
