    geo-rep: Handle EISDIR error during Unlink
    
    During Rename, If Source and Target has same inode then
    Geo-rep unlinks source. But if source is a directory then
    this will fail with below traceback
    
    Traceback (most recent call last):
      File "/usr/libexec/glusterfs/python/syncdaemon/repce.py", line 113, in worker
        res = getattr(self.obj, rmeth)(*in_data[2:])
      File "/usr/libexec/glusterfs/python/syncdaemon/resource.py", line 772,
        in entry_ops
        os.unlink(entry)
    OSError: [Errno 21] Is a directory: '.gfid/12711ebf-7fdc-4f4b-9850-2d75581eb
       452/New folder'
    
    With this patch, if EISDIR, rmdir is tried. Logs error in Slave log in case
    of ENOTEMPTY.
