[svn-r24999] Bugfix: HDFFV-8639
h5diff segfaults with user's files Solution: Added a variable to indicate if real data are in the buffer and will call H5Dvlen_reclaim() only when real data are in the buffer. Tested: with the user provided data files and no more segmentaion fault. Also h5committ tested.
