Description of problem: Mounting client via fuse and then doing a readdir resulted in a crash when the binaries are built with efence


Version-Release number of selected component (if applicable):
3.3.0qa19

How reproducible: The volume was already created. I just tried mounting
glusterfs  client via fuse.


Steps to Reproduce:
1. /gluster/efence/sbin/glusterfs -l /tmp/c1.log -s shortwing --volfile-id=test
--acl /mnt/gfs
2. ls /mnt/gfs

Actual results:
