[PATCH 1/2] ethdev: fix adding invalid mac addr

[Wei Dai <wei.dai@intel.com>]

some customers find adding mac addr to VF sometimes can fail,
but it is still stored in dev->data->mac_addrs[ ]. So this
can lead to some errors that assumes the non-zero entry in
dev->data->mac_addrs[ ] is valid.

Fixes: af75078fece3 ("first public release")
