Comparing m_page_size against kInvalidPageSize was resulting in
a warning about comparing integers with different signs. Since
kInvalidPageSize isn't used anywhere outside of MachVMMemory.cpp,
we can readily transform it into a static const vm_size_t with
the correct value to avoid the sign comparison warnings.
