[PATCH 15/21] fbcon: Consistently protect deferred_takeover with console_lock()

[Daniel Vetter]

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.
