drm/ttm: Don't print error message if eviction was interrupted
[ Upstream commit 8ab3b0663e279ab550bc2c0b5d602960e8b94e02 ]
Avoid printing an error message if eviction was interrupted by,
for example, the user pressing CTRL-C. That may happen if eviction
is waiting for something, like for example a free batch-buffer.
