libdrm/nouveau: unmap before ufree means nvbo->sysmem != NULL, which inbalances cpu_p...

- The bo was mapped with sysmem == NULL, so this means cpu prep is called.
- The bo was unmapped with sysmem != NULL, so this means cpu finish is not called.
- This can lead to a non-zero "cpu writers" count in ttm_bo.
