    in bus_dmamap_load_pglist() try a 32-element array of
    bus_dma_segment_t's before attempting to allocate.

    this hopefully avoids hangs i've had in X since updating
    from netbsd-8 to netbsd-9 that i've tracked down to this
    function failing with ENOMEM.

    XXX: maybe can avoid the alloc entirely by batching these
    calls in 32 segments each.

    XXX pullup-9
