changed H5Pset_fclose_degree to H5F_CLOSE_WEAK

Browse Source 
It seems like it is part of the design of HDF5 virtual datasets that
objects within a file remain opened while the files is aready "closed".
Setting the fclose degree to SEMI would cause the library to bail out.
This commit makes nc_test4/tst_virtual_dataset succeed.
