drm/ttm: replace drm_mm_pre_get() by direct alloc
Instead of calling drm_mm_pre_get() in a row, we now preallocate the node
and then use the atomic insertion functions. This has the exact same
semantics and there is no reason to use the racy pre-allocations.
Note that ttm_bo_man_get_node() does not run in atomic context. Nouveau
already uses GFP_KERNEL alloc in nouveau/nouveau_ttm.c in
nouveau_gart_manager_new(). So we can do the same in
ttm_bo_man_get_node().
