drm/nouveau: make use of the GPUVM's shared dma-resv
DRM GEM objects private to a single GPUVM can use a shared dma-resv.
Make use of the shared dma-resv of GPUVM rather than a driver specific
one.
The shared dma-resv originates from a "root" GEM object serving as
container for the dma-resv to make it compatible with drm_exec.
In order to make sure the object proving the shared dma-resv can't be
freed up before the objects making use of it, let every such GEM object
take a reference on it.
