drm/ttm: Should to return the evict error

[ Upstream commit 4e16a9a00239db5d819197b9a00f70665951bf50 ]

For the evict fail case, the evict error should be returned.

v2: Consider ENOENT case.

v3: Abort directly when the eviction failed for some reason (except for -ENOENT)
 and not wait for the move to finish
