ofproto-dpif: LACP registration should cause revalidation.

Whenever a slave is registered to participate in LACP, it needs to
be revalidated so that it can receive LACP PDUs.  This bug can only
surface in an edge case where a pre-existing interface is added to
a pre-existing bond.  It would be unusual for a controller to do
this.
