Fix compilation error due to API change in HDF5 v1.12

HDF5 v1.12 changed the signature of H5Ovisit_by_name.
Using the new API is actually more efficient, since we can avoid
retrieving fields that aren't needed for the visitor function.

I'm also checking H5_USE_110_API so that anyone explicitly opting
for the old API won't be affected by this change.
