Fix backup NFS share mount with default backup_mount_options

Browse Source 
Now, if backup_mount_options in not set, NFS Backup driver
passes empty dict to RemoteFsClient. It cause an error when
RemoteFsClient mounts the share because it passes '-o {}' params.

According to [1] we should pass None to RemoteFsClient if no
backup_mount_options was specified.
