When PF is put in no-carrier state, iavf VFs will switch to
"in carrier" state due to a link up + a link speed set to 0
(default value if no speed detected).
To be consistent with linux drivers on which PF and VFs are in
same carrier state, updates a link status of VF only if link is up
and speed is different from undefined.
