arm64: Fix -Wunused-function warning when !CONFIG_HOTPLUG_CPU

Browse source

If CONFIG_HOTPLUG_CPU is n, gcc warns:

arch/arm64/kernel/smp.c:967:13: warning: ‘ipi_teardown’ defined but not used [-Wunused-function]
 static void ipi_teardown(int cpu)
             ^~~~~~~~~~~~

Use #ifdef guard this.
