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.
