[dpdk-dev] [PATCH] bus/pci: fix wrong intr_handle.type with uio_pci_generic

[Zhiyong Yang]

In the function rte_pci_ioport_map, if uio_pci_generic is used on X86
platform, pci_ioport_map() is invoked, the operation
ev->intr_handle.type = RTE_INTR_HANDLE_UNKNOWN; is execused directly,
it causes the wrong assignment for uio_pci_generic, the patch fixes it.

Fixes: 756ce64b1ecd ("eal: introduce PCI ioport API")
