    IB/ipath: Fix IRQ for PCI Express HCAs
    
    Commit 51f65ebc ("IB/ipath - program intconfig register using new HT
    irq hook"), which fixed interrupts for HyperTransport HCAs, broke PCI
    Express HCAs, because for those HCAs, the driver uses the value of
    pdev->irq before pci_enable_msi() and ends up getting a totally bogus
    IRQ number.  Fix this by using the value of pdev->irq after
    pci_enable_msi().
