Non root user failed to delete empty directory which has no read permission, we used at client side "fuse.glusterfs" mount

Version-Release number of selected component (if applicable):
glusterfs-3.6.2

How reproducible:
create a director, remove the read permission and try to delete it

[root@CLA-0(test) /root]
# su - iotest
[iotest@CLA-0(test) /home/iotest]
#  mkdir -p ldq
[iotest@CLA-0(test) /home/iotest]
# chmod -r ldq
[iotest@CLA-0(test) /home/iotest]
# ls -l
total 4
d-wx--x--x 2 iotest iotest 4096 Aug 17 11:08 ldq
[iotest@CLA-0(test) /home/iotest]
# ls ldq/
ls: cannot open directory ldq/: Permission denied
[iotest@CLA-0(test) /home/iotest]


Steps to Reproduce:
1. su - itest
2. mkdir -p ldx 
3. chmod -r ldx
