cluster/afr: For entry self heal, mark all source bricks
Problem: Whenever a new brick is added into a replicate volume, all source bricks are not marked as source. Only one of them is marked as source. Here marked as source refers to adding extended attribute at the backend of a file corresponding to the newly added brick. As well as source bricks should point to the newly added brick so that heal can be triggered. Fix: All source bricks will now point to newly added bricks and heal can be triggered based on the extended attributes.
