x86: fix build warning when CONFIG_NUMA not defined.

Impact: fix build warning

The macro cpu_to_node did not reference it's argument, and instead
simply returned a 0.  This causes a "unused variable" warning if
it's the only reference in a function (show_cache_disable).

Replace it with the more correct inline function.
