geo-rep: performance improvement while syncing renames with existing gfid
Problem:
The bug[1] addresses issue of data inconsistency when handling RENAME with
existing destination. This fix requires some performance tuning considering
this issue occurs in heavy rename workload.
Solution:
If distribution count for master volume is one do not verify op's on
master and go ahead with rename.
The performance improvement with this patch can only be observed if
master volume has distribution count one.
