drm/nouveau/prime: Extend DMA reservation object lock
Prior to commit 019cbd4a ("drm/nouveau: Initialize GEM object before TTM object"), the reservation object was locked across all of the buffer object creation. After splitting nouveau_bo_new() into separate nouveau_bo_alloc() and nouveau_bo_init() functions, the reservation object is passed to the latter, so the lock needs to be held across that function as well.
