drm/nouveau: do not allow negative sizes for now The API allows up to 64-bits allocations, but size is handled as int inside nouveau almost everywhere. Until this is fixed it's better to prevent negative sizes. The 256 kB before INT_MAX is paranoia, because of the large page aligning below that could flip it above INT_MAX.
