Otherwise it seems like we can get stuck with concurrent waiters. Right now this /shouldn't/ be a problem, since all pending pageflip waiters are serialized by the one mode_config.mutex, so there's at most on waiter. But better paranoid than sorry, since this is tricky code.

v2: WARN_ON(waitqueue_active) before waiting, as suggested by Chris Wilson.

Oops, this one is for i915 only, rather unrelated and merged already anyway. Please disregard. -Daniel
