Subject: [PATCH] x86/cpu: Remove redundant CONFIG_NUMA guard around numa_add_cpu()

Remove unnecessary CONFIG_NUMA ifdef around numa_add_cpu() since the
function is already properly handled in numa.h for both NUMA and
non-NUMA configurations. For !CONFIG_NUMA builds, numa_add_cpu() is
defined as an empty function.

Simplify the code without any functionality change.

Testing: Make CONFIG_NUMA=n build
