nfp: fix PCI device info retrieval

nfp: fix PCI device info retrieval

The NFP driver (unlike other PCI devices) was not copying the pci info
from the pci_dev to the eth_dev.  This would make the driver_name be
null (and other unset fields) when application uses dev_info_get.

This was found by code review; do not have the hardware.
