sctp: Correclty set changeover_active for SFR-CACC
Right now, any time we set a primary transport we set
the changeover_active flag. As a result, we invoke SFR-CACC
even when there has been no changeover events.
Only set changeover_active, when there is a true changeover
event, i.e. we had a primary path and we are changing to
another transport.
