description:
We explicitly close LCP when going to state CLOSED, so we better open
it again when going from INITIAL to STARTING. This has been done for
passive or auto-conecting interfaces always, but not for permanent
ones.

This fixes session reestablishement for PPPoE interfaces without LINK1 set,
and probably also closes PR kern/11161.

Thanks to Jared D. McNeill and Ross Harvey for sugesting debug methology.
