The cpuhp_is_ap_state() function is no longer called outside of the
CONFIG_SMP #ifdef section, causing a harmless warning:
kernel/cpu.c:129:13: error: 'cpuhp_is_ap_state' defined but not used
[-Werror=unused-function]
This moves the function into the #ifdef to get a clean build again.
Fixes: 17a2f1ced028 ("cpu/hotplug: Merge cpuhp_bp_states and cpuhp_ap_states")
