[svn-r4397] Purpose:

    Bug fix
Description:
    SAF test code exposed an error in the HDF5_MPI_OPT_TYPES
    code.  The SAF code was doing collective write to chunked
    storage dataset.  Some processes wanted to flush some chunk
    while some other processes were doing something else but the
    HDF5_MPI_OPT_TYPES code thought the chunk flushing were collective
    calls since it only looked at the condition when H5Dwrite
    was called.  So, it hanged when doing MPI_File_setview.
    For now, turned off the HDF5_MPI_OPT_TYPES code so that the
    SAF code would work.  More long term fix later.
Platforms tested:
    modi4(pp)
