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.
