[svn-r11891] Purpose: Small bug fix

Description: h5_group example didn't work on VMS; it turned out
             that a group was not closed and since the default
             file close degree is "weak", file was not closed either.
             When program attempted to open the same file, system reported
             an error since the file was "locked by another user".
             UNIX systems apperently do not care and open the same file
             without any problem.

Solution: Added H5Gclose calls.

Platforms tested: VMS server and heping
