hdf5_ep

[svn-r1059] Purpose:
    Bug fix

Problem:
    Did a H5get_type() on a dataset of committed type without doing
    the associated H5Tclose().  This caused an abort to occur during the
    atexit() phase of the h5toh4 converter.

Solution:
    Execute the associated H5Tclose().

Platform tested:
    Solaris2.5
