I messed up while rebasing patches and didn't test every intermediate
patch as I should have. The next patch in the series fixes this.
If anyone wants to fix this before merging further upstream, remove the
offending line in this commit and reintroduce it in the next commit in
the series. At this point in the series GFX8 KFD SDMA isn't supposed to
work anyway.

Felix
