drm/nouveau: prime: fix refcount underflow



[ Upstream commit a9bf3efc33f1fbf88787a277f7349459283c9b95 ]

Calling nouveau_bo_ref() on a nouveau_bo without initializing it (and
hence the backing ttm_bo) leads to a refcount underflow.

Instead of calling nouveau_bo_ref() in the unwind path of
drm_gem_object_init(), clean things up manually.
