[svn-r10881] Purpose: Bug fix

Description: After recent fix of family driver bug(#213), some failure
was discovered on sol and kelgia in daily test.  Family files can't be
opened by hdf5/tools/misc/repart_test.c.  It turned out to be the
destination size of "off_t" type wasn't passed in through H5Pset()
correctly.

Solution: In tools/misc/h5repart.c, copy the destination size to a
variable of "hsize_t" type and pass in to H5Pset().

Platforms tested: sol and kelgia where the failure was discovered.
