ethdev: read link state interrupt without link update service

Browse Source 
It is now possible to read link status updated by interrupt without
having manual link_update() service provided by the PMD.
Indeed link_update() is useless in interrupt case. So check of this
function pointer must be done in the interrupt case only.
