nfp: validate the return code from dev_queue_xmit()

Browse Source 
[ Upstream commit c8ba5b91a04e3e2643e48501c114108802f21cda ]

dev_queue_xmit() may return error codes as well as netdev_tx_t,
and it always consumes the skb.  Make sure we always return a
correct netdev_tx_t value.

Fixes: eadfa4c3be99 ("nfp: add stats and xmit helpers for representors")
