domain: fix unintentional deprecation warning

646e5a4 changed the way that the domain hook callback
is called. Previously, the callback was only used in the case that
async_hooks were *not* being used (since domains already integrate
with async hooks the way they should), and the corresponding
deprecation warning also only emitted in that case.

However, that commit didn’t move that condition along when the code
was ported from C++ to JS. As a consequence, the domain hook callback
was used when it wasn’t necessary to use it, and the deprecation
warning emitted accidentally along with it.
