Description of problem:
If the I/O is running during the geo-rep start time, then few of the files are
not synced to slave.


Version-Release number of selected component (if applicable):
glusterfs-3.6.0.28-1.el6rhs.x86_64

How reproducible:
Seems to be reproducible frequently.

Steps to Reproduce:
1. create master and slave volume and start file creation in master.
2. Create and start geo-rep.
3. Wait for files to sync to slave.

Actual results:
Few files are skipped while syncing. As a result, slave will not be having all
the files in master.

Expected results:
All the files in master should be synced to slave in any case.

Additional info:
