Well this is not really bsd specific, as people who rely on
rte_pci_dev_ids.h header to find devices that must be bound to igb_uio and
consort, will also benefit from this fix.
By the way, I am working on removing these device ids from the eal, since
the pmds should be the only one that maintain their devices ids list.
Will send some patches soon.
