fix trunk breakage that sneaked in with the lacp diff:

- don't use in-kernel IFMEDIA ioctls in lacp and remove two KASSERTs
that caused reliable panics - the lacp key can be locally assigned and
we don't need to query the media subtype here.

- unbreak failover/loadbalance/broadcast status handling.
