the gem object rfb->base.obj[0] is get according to num_planes
in amdgpufb_create, but is not put according to num_planes

[How]
put rfb->base.obj[0] in amdgpu_fbdev_destroy according to num_planes

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/amdgpu: corrige la fuga de refcount [Por qué] el objeto gema rfb->base.obj[0] se obtiene según num_planes en amdgpufb_create, pero no se coloca según num_planes en amdgpufb_create num_planes [Cómo] poner rfb->base.obj[0] en amdgpu_fbdev_destroy según num_planes
