[capi-unixdcr] replica items mismatch on destination cluster

http://qa.hq.northscale.net/job/centos_x64--31_01--uniXDCR-P1/32/consoleFull

[Test]
./testrunner i centos_x6431_01-uniXDCR-P1.ini GROUP=CHAIN,get-cbcollect-info=True,get-logs=False,stop-on-failure=False,get-coredumps=True -t xdcr.uniXDCR.unidirectional.replication_with_firewall_enabled,items=100000,rdirection=unidirection,ctopology=chain,GROUP=CHAIN;P1

[Test Steps]
1. Setup CAPI-Unixdcr Source and Destination cluster. (4-4 Nodes, bucket- default)
2. Load 1M items on Source cluster.
3. Wait for 10 second. Enable firewall on destination cluster.
4. Disable firewall on destination cluster.
5. Verify items on both the ends. Current items are expected -> 1M
6. replica items are 99958 while 1M were expected.
