RDMA/mlx5: Follow rb_key.ats when creating new mkeys

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.
