fbcon: Consistently protect deferred_takeover with console_lock()
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.
