cpu/hotplug: Adjust misplaced smb() in cpuhp_thread_fun()
commit f8b7530aa0a1def79c93101216b5b17cf408a70a upstream.
The smp_mb() in cpuhp_thread_fun() is misplaced. It needs to be after the
load of st->should_run to prevent reordering of the later load/stores
w.r.t. the load of st->should_run.
Fixes: 4dddfb5faa61 ("smp/hotplug: Rewrite AP state machine core")
