Description of problem:
Accessing the mount point gives I/O errors

Version-Release number of selected component (if applicable):
Mainline

How reproducible:
always

Steps to Reproduce:
1. created a distribute volume with 1 brick
2. on the mount point ran the following scripts
 a. for i in {1..100} ; do dd if=/dev/urandom of=$i bs=1024 count=1000; done
 b. for i in {101..200}; do mkdir $i; cd $i; touch $i;done

3. Now access the mount point
  
Actual results:
I/O errors are shown  and log shows "detected cyclic loop formation during inode linkage."

Expected results:
