drm/nouveau: uvmm: remove dedicated VM pointer from VMAs
VMAs can find their corresponding VM through their embedded struct
drm_gpuva which already carries a pointer to a struct drm_gpuva_manager
which the VM is based on. Hence, remove the struct nouveau_uvmm pointer
from struct nouveau_uvma to save a couple of bytes per mapping.
