i40e: don't add zero MAC filter
When VFs are created, the MAC address defaults to all zeros, indicating
to the VF driver that it should use a random MAC address. However, the
PF driver was incorrectly adding this zero MAC to the filter table,
along with the VF's randomly generated MAC address.
Check for a good address before adding the default filter. While we're
at it, make the error message a bit more useful.
