Replace open call to WANT_FD with newly added API llapi_root_path_open()

Example: A call to WANT_FD like below

if (path_or_device[0] == '/')
        rc = get_root_path(WANT_FD, NULL, &mnt_fd,
                           (char *)path_or_device, -1, NULL, NULL);
else
        rc = get_root_path(WANT_FD, (char *)path_or_device,
                   &mnt_fd, NULL, -1, NULL, NULL);
