Description of problem:
=========================
In a distribute-replicate volume when 'rm -rf *' is performed from multiple mounts, On some directories rm -rf fails with message "rm: cannot remove `A482/B3/C9': Is a directory" 

Unlink call is sent on the directory rather than "rmdir"

How reproducible:
====================
Often

Steps to Reproduce:
====================
1. Create distribute-replicate volume. Start the volume.

2. Create 2 fuse mounts and 2 nfs mount or all 4 fuse mounts. 

3. Create directories ( mkdir -p A{1..1000}/B{1..20}/C{1..20} )

4. From all the mount points execute "rm -rf *"

Actual results:
=================
root@dj [Jul-02-2014- 1:13:53] >rm -rf *
rm: cannot remove `A11': Directory not empty
rm: cannot remove `A111': Directory not empty
rm: cannot remove `A137': Directory not empty
rm: cannot remove `A151/B18': Directory not empty
rm: cannot remove `A153': Directory not empty
rm: cannot remove `A163': Directory not empty
rm: cannot remove `A204': Directory not empty
rm: cannot remove `A480/B16': Directory not empty
rm: cannot remove `A480/B17/C10': Is a directory
rm: cannot remove `A481/B15': Directory not empty
rm: cannot remove `A481/B19': Directory not empty
rm: cannot remove `A481/B5': Directory not empty
rm: cannot remove `A481/B14': Directory not empty
rm: cannot remove `A482/B3/C9': Is a directory

Expected results:
==================
unlink call shouldn't be sent on directories. 

Additional info:
==================
ls -l on that directory is returning "No Such File or Directory"

root@dj [Jul-02-2014- 1:52:45] >ls -l A482/B3/C9
ls: cannot access A482/B3/C9: No such file or directory
