Per an off-list discussion, we agreed to not have TDH.SYS.UPDATE do the
TDH.EXT.INIT work internally so  that another VMM can have more flexibility. So
we now need to go back to something like we had in v1 where it is called after
update. But given the change in error codes for TDH.EXT.INIT, I think we still
don't need to save the ext_required metadata field? We can just call it
unconditionally, right? So it should still be a bit simpler than v1.
