    cluster/ec: correctly handle end of file for seek
    
    When a SEEK_HOLE was issued near to the end of file, sometimes an
    offset beyond the end of file was returned. Another problem was that
    using some offsets greater than the end of file returned successfully
    instead of failing with ENXIO.
