For virtio legacy device, testpmd startup fails when using
uio_pci_generic. The issue is caused by invoking the function
pci_ioport_map. The right intr_handle.type is already set before
calling it, we should avoid overwriting the default value "RTE_
INTR_HANDLE_UNKNOWN" in it. Besides, the removal has no harm to
other cases since it already is set to this value (0) at init.
