For virtio legacy device, testpmd startup fails when using uio_pci_generic.
The issue is caused by invoking the function pci_ioport_map. The correct
value of intr_handle.type is already set before calling it, we should avoid
overwriting the default value "RTE_INTR_HANDLE_UNKNOWN" in this function.
Besides, the removal has no harm to other cases because it is set to 0 by a
memset on the whole struct during allocation in the function pci_scan_one.
Such assignments are removed in the meanwhile in pci_uio_map_resource(),
pci_vfio_map_resource_primary() and pci_vfio_map_resource_secondary() in
order to keep consistencies and avoid future questions.
