commit 73911426aaaadbae54fa72359b33a7b6a56947db upstream.
All other opcodes correctly check if this is set and -EINVAL if it is and they don't support that field, for some reason the these were forgotten.
This was unified a bit differently in the upstream tree, but had the same effect as making sure we error on this field. Rather than have a painful backport of the upstream commit, just fixup the mentioned opcodes.
