From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
On the case where nn->eth_port is null the warning message
is printing the port by dereferencing this null pointer.
Remove the deference to avoid a crash when printing the
warning message.
Detected by CoverityScan, CID#1426198 ("Dereference after null check")
Fixes: ce22f5a2cbe3c627 ("nfp: separate high level and low level NSP headers")
