When we call drm_vblank_off() at DPMS off time (to wake any clients so they don't hang) we need to make sure interrupts are actually disabled. If drm_vblank_off() gets called before the vblank usage timer expires, it'll prevent the timer from disabling interrupts since it also clears the vblank_enabled flag for the pipe.
