smp/hotplug: Move step CPUHP_AP_SMPCFD_DYING to the correct place
Commit 31487f8328f2 ("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: 31487f8328f2 ("smp/cfd: Convert core to hotplug state machine")
