net/nfp: fix live MAC changes not supported

Browse Source 
Some NFP firmwares support live changes to the MAC address, but
this is not always true and the firmware advertises it accordingly.

This patch checks if firmware does not support live changes and
sets RTE_ETH_DEV_NOLIVE_MAC_ADDR in that case.
