[svn-r22805] Purpose:
    HDFFV-8012 - h5repack changes max dims and cause failure if only "-f none" is used without changing layout for chunked dataset when a chunk dim is bigger than a dataset dim

Description:
    "h5repack -f <obj>:NONE <file.h5> out.h5" command failed if source file contains chunked dataset and a chunk dim is bigger than a dataset dim. 
    Another issue is that the command changed max dims if chunk dim is smaller than the dataset dim. 
    These issue occurred when dataset size is smaller than 64k (compact size limit)
    Fixed them.

Tested: 
    jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE),  Windows (32-LE cmake), cmake (jam)
