Christian König 546486c5b1 drm/ttm: fix LRU handling in ttm_buffer_object_transfer ...

[ Upstream commit d6e820fcd4 ]

We need to set the NO_EVICT flag on the ghost object or otherwise we are
adding it to the LRU.

When it is added to the LRU we can run into a race between destroying
and evicting it again.
