6.6-stable review patch. If anyone has any objections, please let me know.

From: Jason Gunthorpe jgg@nvidia.com
commit f637040c3339a2ed8c12d65ad03f9552386e2fe7 upstream.
When a cache ent already exists but doesn't have any mkeys in it the cache will automatically create a new one based on the specification in the ent->rb_key.
ent->ats was missed when creating the new key and so ma_translation_mode was not being set even though the ent requires it.
