glusterd : fix client io-threads option for replicate volumes
Problem: Commit ff075a3d6f9b142911d25c27fd209838782bfff0 disabled loading client-io-threads for replicate volumes (it was set to on by default in commit e068c1997314046658dd502e9118dab32decf879) due to performance issues but in doing so, inadvertently failed to load the xlator even if the user explicitly enabled the option using the volume set command. This was despite returning returning sucess for the volume set. Fix: Modify the check in perfxl_option_handler() and add checks in volume create/add-brick/remove-brick code paths, tying it all to GD_OP_VERSION_3_12_2.
