geo-rep: Fix Permission denied traceback on non root setup

Problem:
While syncing rename of directory in hybrid crawl, geo-rep
crashes as below.

Traceback (most recent call last):
  File "/usr/local/libexec/glusterfs/python/syncdaemon/repce.py", line 118, in worker
    res = getattr(self.obj, rmeth)(*in_data[2:])
  File "/usr/local/libexec/glusterfs/python/syncdaemon/resource.py", line 588, in entry_ops
    src_entry = get_slv_dir_path(slv_host, slv_volume, gfid)
  File "/usr/local/libexec/glusterfs/python/syncdaemon/syncdutils.py", line 687, in get_slv_dir_path
    [ENOENT], [ESTALE])
  File "/usr/local/libexec/glusterfs/python/syncdaemon/syncdutils.py", line 546, in errno_wrap
    return call(*arg)
PermissionError: [Errno 13] Permission denied: '/bricks/brick1/b1/.glusterfs/8e/c0/8ec0fcd4-d50f-4a6e-b473-a7943ab66640'

Cause:
Conversion of gfid to path for a directory uses readlink on backend
.glusterfs gfid path. But this fails for non root user with
permission denied.

Fix:
Use gfid2path interface to get the path from gfid
