[PATCH 03/17] drm/nouveau: add reservation to nouveau_gem_ioctl_cpu_prep

Apart from some code inside ttm itself and nouveau_bo_vma_del, this is the only place where ttm_bo_wait is used without a reservation. Fix this so we can remove the fence_lock later on. After the switch to rcu the reservation lock will be removed again. Signed-off-by: Maarten Lankhorst ---
