    geo-rep: Handle ERANGE error during listxattr

    llistxattr in Geo-rep is two syscall instead of one

    SIZE = llistxattr(PATH, &BUF, 0);
    BUF = create_buf(SIZE);
    _ = llistxattr(PATH, &BUF, SIZE);

    So if any new xattrs added just after first call by any other worker,
    second syscall will fail with ERANGE error.

    Now Geo-rep sends BUF with large size(256*100) and gets value
    with only one syscall. Raises OSError if fails with ERANGE error
    even after sending large BUF.
