topology: Fix compilation warning when not in SMP

The topology_##name() macro does not use its argument when CONFIG_SMP is not
set, as it ultimately calls the cpu_data() macro.

So we avoid maintaining a possibly unused `cpu' variable, to avoid the
following compilation warning:

  drivers/base/topology.c: In function ‘show_physical_package_id’:
  drivers/base/topology.c:103:118: warning: unused variable ‘cpu’ [-Wunused-variable]
   define_id_show_func(physical_package_id);

  drivers/base/topology.c: In function ‘show_core_id’:
  drivers/base/topology.c:106:106: warning: unused variable ‘cpu’ [-Wunused-variable]
   define_id_show_func(core_id);

This can be seen with e.g. x86 defconfig and CONFIG_SMP not set.
