[Nouveau] 3.12 nvidia switcheroo regression

Hi Marcin et al,

When booting my Macbook Pro into 3.12 and powering off the Nvidia GPU, we
see nouveau try to dequeue an item which isn't present, leading to a
page-not-present fault. 3.11 works just nice.

It looks like I should add some debug, as there aren't event
enqueuing/dequeueing debug flags, or as you suggest?
