    PCI: handle PCI->PCIe bridges as well in alloc_pdev()
    
    It's not clear why the enumerator was omitted, as these clearly shouldn't
    take the "default" path (issuing a warning). Handle them the same as
    legacy and PCIe->PCI bridges.
    
    Fixes: e7e08d86ad2f ("IOMMU/PCI: consolidate pdev_type() and cache its 
result for a given device")
