[svn-r14709] Fixed the assert() failures (development mode) from Wed. daily tests:
Add 2 more parameters to H5HF_man_iblock_size() (parent iblock and parent entry)
for passing onto H5HF_iblock_man_iblock_protect().
This bug was there before but was revealed now by exercising the recursive part of the code from the new
"h5stat_newgrat.h5".
Tested on kagiso, smirom and linew with --disable-production.
