Merge pull request #1516 in HDFFV/hdf5 from ~DEROBINS/hdf5_der:valgrind_fixes to develop * commit '5f1f231310bcb3278f11a51e1ea47782f6ee3235': Updated H5Dio.c comment. Fixed a valgrind issue with the unprotect log message. The logging call was placed after the point where the cache entry was freed. The fix was to just use the entry's address directly in the log call instead of the entry itself. Fixed a bug revealed by the dtransform test. A datatype transform buffer needed to be calloc'd.
