Compression is broken for SVM and for devcoredump when reading out BOs.

Marking the first two patches as fixes. One option could be to drop
patch 1 and proceed with just the last two patches as fixes, if we
decide we're confident in SVM with compression.

Tested with [1]. The append memory copy compression sections fail on
drm-tip and pass after this series.
