iavf: Do not publish link-up while stoppedHEADmain

A PF link event remains cached while a VF is administratively down.
Media status queries called iavf_update_link_status() and published
that cached state as link-up, while the stopped admin path immediately
published link-down.  Consumers reacting to link events could turn
this into an unbounded notification loop and prevent interface detach
from draining its link-state task.

Keep the cached PF state, but only publish link-up after iflib has
marked the VF running.  A subsequent admin pass publishes the cached
state after a successful initialization.
