drm/nouveau/nouveau_bo: fix potential memory leak in nouveau_bo_alloc()

nouveau_bo_alloc() allocates a memory chunk for "nvbo" with kzalloc().
When some error occurs, "nvbo" should be released. But when
WARN_ON(pi < 0)) equals true, the function return ERR_PTR without
releasing the "nvbo", which will lead to a memory leak.

We should release the "nvbo" with kfree() if WARN_ON(pi < 0)) equals true.
