    pci: don't overwrite multi functio bit in pci header type. · b80d4a98

    Don't overwrite pci header type.
    Otherwise, multi function bit which pci_init_header_type() sets
    appropriately is lost.
    Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero
    which is already zero cleared.
    
    how to test:
    run qemu and issue info pci to see whether a device in question is
    normal device, not pci-to-pci bridge.
    This is handy because guest os isn't required.
