drm/nouveau: fix notifier memory corruption bug

nouveau_bo_wr32 expects offset to be in words, but we pass value in bytes,
so after commit 73412c3854c877e5f37ad944ee8977addde4d35a ("drm/nouveau: allocate
kernel's notifier object at end of block") we started to overwrite some memory
after notifier buffer object (previously m2mf_ntfy was always 0, so it didn't
matter it was a value in bytes).
