async: Split async_schedule_node_domain() 

commit 6aa09a5bccd8e224d917afdb4c278fc66aacde4d upstream.

In preparation for subsequent changes, split async_schedule_node_domain()
in two pieces so as to allow the bottom part of it to be called from a
somewhat different code path.

No functional impact.
