Previously, due to a bug in glusterd, executing the `gluster volume set <volname> client-io-threads on` command on a replicate volume returned success without actually enabling it in the client graph. This updates fixes that bug, and executing the `gluster volume set <volname> client-io-threads on` command provides a correct success result and ensures that the translator is loaded on the client graph.

I don't think the 'Hence' is appropriate. The bug was not that client-io-threads translator was not loaded in a replicated volume by default. The problem was when you explicitly set it on, it returned success but still did not enable it/load it in the client graph.
