Revert "cpuset: Make cpuset hotplug synchronous"

This reverts commit 9a3980b63e49c71579abecadd1d65414401c174e.

This and the previous commit led to another circular locking scenario
and the scenario which is fixed by this commit no longer exists after
1e49187703a8 ("workqueue/hotplug: simplify workqueue_offline_cpu()")
which removes work item flushing from hotplug path.

Revert it for now.
