cluster/afr: Provide option to disable readdir failover
In a replica pair unlike files, directories may not have their content in same order, so readdir for same (offset, size) may not give same entries on both the sobvolumes of replica pair. Switching over from one subvolume to another may not be a good idea sometimes. It may lead to duplicate entries or fewer entries or both. This patch provides a way to disable readdir-failover so that applications like rebalance can retry if they want to.
