Description of problem:
=======================
I have seen below timer error in rebalance logs after remove-brick completion,
however I didn't see any functionality impact here, remove-brick rebalance completed without any failures.

Version-Release number of selected component (if applicable):
3.8.4-32.el7rhgs.x86_64

How reproducible:
Reporting the first occurrence.

Steps to Reproduce:
===================
1) Create a distrbuted-replicate volume and start it.
2) cifs mount the volume on multiple clients.
3) From client-1 -> start creating files and from a diff terminal start continuous lookups.
   wait for some time and from client-2 -> Start creating hardlinks
4) Remove few bricks and wait till the remove-brick operation completes.

After completion of remove-brick, check rebalance logs and you will see above timer error messages.

Actual results:
===============
Seeing timer errors in rebalance logs.

Expected results:
=================
No timer error messages should come in rebalance logs.
