this commit fixes an issue observed with romio314 and the hdf5 1.10.x testsuite. The ADIOI_Datatype_iscontig() routine in romio314/src/io_romio314_module.c will now return for a datatype of size 0 that it is contiguous, even if the extent of the datatype is non-zero. This avoids a segmentation fault observed in the ADIOI_Flatten routine, and fixes this particular with the hdf5 1.10.x testsuite in OpenMPI with romio314.

@edgargabriel This periodically happens -- sometimes our email checker bot gets a malformed request from Github and gets confused. I just re-triggered it on the back end, and now everything is good. |

will now return for a datatype of size 0 that it is contiguous, even if the extent
of the datatype is non-zero. This avoids a segmentation fault observed in the
ADIOI_Flatten routine, and fixes this particular with the hdf5 1.10.x testsuite in
OpenMPI with romio314.
