Olivier Matz caccf8b318 ethdev: return diagnostic when setting MAC address 
Change the prototype and the behavior of dev_ops->eth_mac_addr_set(): a
return code is added to notify the caller (librte_ether) if an error
occurred in the PMD.

The new default MAC address is now copied in dev->data->mac_addrs[0]
only if the operation is successful.

The patch also updates all the PMDs accordingly.
