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.
