cluster/ec: Non-disruptive upgrade on EC volume fails
Problem: Enabling optimistic changelog on EC volume was not handling node down scenarios appropriately resulting in volume data inaccessibility. Solution: Update dirty xattr appropriately on good bricks whenever nodes are down. This would fix the metadata information as part of heal and thus ensures data accessibility.
