The branch is explicitly taken if ttm == NULL which means that to avoid
a null pointer reference the ttm object can not be used inside. Switch
back to dst_mem to avoid kernel oops'es.
This fixes kernel oops'es with any buffer objects which don't have ttm_tt,
e.g. with vram based screen objects on vmwgfx.

Should I push it to drm-misc-fixes?
If you're not too busy that'd be great. Otherwise I can do it tomorrow.
Done.
