Record densify bug

I think I've found bug in file record_datatype.cxx.

Datatype_uptr Record_datatype::densify() const
{
    long displacement = 0;
    vector<Record_datatype::Member> densified_members;
    for (auto&& member : m_members) {
        densified_members.emplace_back(displacement, member.type().densify(), member.name());
        displacement += densified_members.back().type().datasize();
    }
    return unique_ptr<Record_datatype> {new Record_datatype{move(densified_members), m_buffersize}};
}

We are returning densified record datatype, but size of the new record is m_buffersize, shouldn't it be m_datasize?
