drm/nouveau: Initialize GEM object before TTM object
TTM assumes that drivers initialize the embedded GEM object before
calling the ttm_bo_init() function. This is not currently the case
in the Nouveau driver. Fix this by splitting up nouveau_bo_new()
into nouveau_bo_alloc() and nouveau_bo_init() so that the GEM can
be initialized before TTM BO initialization when necessary.
Fixes: b96f3e7c8069 ("drm/ttm: use gem vma_node")
