    pci: fix pci_get_pdev() to always account for the segment
    
    When a domain parameter is provided to pci_get_pdev() the search
    function would match against the bdf, without taking the segment into
    account.
    
    Fix this and also account for the passed segment.
    
    Fixes: 8cf6e0738906 ('PCI: simplify (and thus correct) 
pci_get_pdev{,_by_domain}()')
