[OpenAFS] Inconsistency in displayed volumes size

[Hartmut Reuter]

On AFS fileervers with then NAMEI-Interface (for Linux always true) a
certain amount of disk space is consumed by the directories in the
/vicep-Partition. Depending on how big the files are in average and how
many files belong to a volume an overhead of 6 to 10 % seems reasonable.
