Merge pull request #38 in HDF5VOL/daos-vol from ~NFORTNE2/daos-vol:master to master * commit '46f6fd3160e6554326b3ff343113ae8bbef42a79': Re-add removed struct initialization. NULL is guaranteed to compare equal to (void *)0 but that does not mean it is implemented with all 0 bits, therefore we cannot rely on calloc to set pointer in the struct to NULL. DAOS_HDL_INVAL is not guaranteed to remain 0 to my knowledge.
