Title
drm/nouveau: prime: fix refcount underflow
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: prime: fix refcount underflow
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.
(cherry picked from commit 1b93f3e89d03cfc576636e195466a0d728ad8de5)
