Bug 1609224

Description of problem:
========================
While moving multiple temporary files to the same destination concurrently, writes and reads on the same dest file fails with ESTALE and ENOENT.

Version-Release number of selected component (if applicable):
3.12.2-14.el7rhgs.x86_64

How reproducible:
always

Steps to Reproduce:
====================
1) Create a distributed-replicated volume and start it.
2) FUSE mount it on multiple clients.
3) From few clients execute,

"while true; do uuid="`uuidgen`"; echo "some data" > "test$uuid"; mv "test$uuid" "test" -f; done"
From other clients, keep sending lookups.
4) With step-3 in-progress, do writes and reads to the destination file "test".

[root@dhcp37-109 fuse]# while true; do cat /etc/redhat-release >> test;cat test;done
