drm/xe: Keep walking on SVM eviction failure

Browse source

The desired behavior for SVM eviction failures, which can occur due to
various uncontrollable races, is for TTM to continue walking the LRU
list and look for another eviction candidate. This is expressed by
returning -ENOSPC from the ->move() callback.

Adjust the SVM eviction failure path because of races in ->move() to
return -ENOSPC so that TTM continues searching for another buffer to
evict.
