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(). Signed-off-by: Roland Dreier <rolandd@cisco.com>
