smp/hotplug: Move step CPUHP_AP_SMPCFD_DYING to the correct place

Commit 31487f8328 ("smp/cfd: Convert core to hotplug state machine")
accidently put this step on the wrong place. The step should be at the
cpuhp_ap_states[] rather than the cpuhp_bp_states[].

grep smpcfd /sys/devices/system/cpu/hotplug/states
 40: smpcfd:prepare
129: smpcfd:dying

"smpcfd:dying" was missing before.
So was the invocation of the function smpcfd_dying_cpu().

Fixes: 31487f8328 ("smp/cfd: Convert core to hotplug state machine")
