    Fix missing DMA32 limit
    
    Rumpdisk needs to allocate dma32 memory areas, so we do always need this
    limit.
    
    The non-Xen x86_64 case had a typo, and the 32bit PAE case didn't have
    the DMA32 limit.
    
    Also, we have to cope with VM_PAGE_DMA32_LIMIT being either above or below
    VM_PAGE_DIRECTMAP_LIMIT depending on the cases.
