Description of problem:
Refresh config failed while exporting subdirectories within a volume.

Version-Release number of selected component (if applicable):
nfs-ganesha-2.4.0-2.el7rhgs.x86_64
glusterfs-server-3.8.4-3.el7rhgs.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Create a ganesha cluster, create a volume and enable nfs-ganesha on that
volume.
2. Mount the volume and create subdirectories.
3. Edit the export.conf file to export subdirectories within the volume.
    conf file path:
/var/run/gluster/shared_storage/nfs-ganesha/exports/export.testvol1.conf
4. Run refresh config.
    /usr/libexec/ganesha/ganesha-ha.sh --refresh-config
/var/run/gluster/shared_storage/nfs-ganesha/ testvol1

Actual results:

Refresh config failed.

Expected results:
Refresh config should succeed and subdirectory should be exported.

Additional info:

Edited export.conf file:
-------------------------

EXPORT{
      Export_Id = 2;
      Path = "/testvol1/user2/dir0";
      FSAL {
           name = GLUSTER;
           hostname="localhost";
          volume="testvol1";
          volpath="/user2/dir0";
           }
      Access_type = RW;
      Disable_ACL = true;
      Squash="No_root_squash";
      Pseudo="/testvol1_ps";
      Protocols = "3", "4" ;
      Transports = "UDP","TCP";
      SecType = "sys";
     }
