IB/qib: Clean up unnecessary MSI/MSI-X capability find
PCI core will initialize device MSI/MSI-X capability in
pci_msi_init_pci_dev(). So device drivers should use
pci_dev->msi_cap/msix_cap to determine whether a device supports
MSI/MSI-X instead of using pci_find_capability(pci_dev,
PCI_CAP_ID_MSI/MSIX). Access to PCIe device config space again will
consume more time.
