glusterd: volume get fixes for client-io-threads & quorum-type
1. If a replica volume created on glusterfs-3.8 was upgraded to glusterfs-3.12, `gluster vol get volname client-io-threads` displayed 'on' even though it wasn't and the xlator wasn't loaded on the client-graph. This was due to removing certain checks in glusterd_get_default_val_for_volopt as a part of commit 47604fad4c2a3951077e41e0c007ceb979bb2c24. Fix it. 2. Also, as a part of op-version bump-up, client-io-threads was being loaded on the clients during volfile regeneration. Prevent it. 3. AFR assumes quorum-type to be auto in newly created replic 3 (odd replica in general) volumes but `gluster vol get quorum-type` displays 'none'. Fix it.
