drm/ttm: Fix a regression causing kernel oops'es
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.
