[ Upstream commit 43553559121ca90965b572cf8a1d6d0fd618b449 ]
This shouldn't be a problem in practice since until we've actually taken over the console there's nothing we've registered with the console/vt subsystem, so the exit/unbind path that check this can't do the wrong thing. But it's confusing, so fix it by moving it a tad later.
