Jaswinder Singh Rajput b206525ad1 x86: k8 convert node_to_k8_nb_misc() from a macro to an inline function
Converting node_to_k8_nb_misc() from a macro to an inline function
makes compiler see the 'node' parameter in the !CONFIG_K8_NB too,
which eliminates these 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’
