    cluster/ec: Wind unlock fops at all cost
    
    Problem:
    While files are being created if more than redundancy number of bricks
    go down, then unlock for these fops do not go to the bricks. This will
    lead to stale locks leading to hangs.
    
    Fix:
    Wind unlock fops at all costs.
