    ikev2: cleanup the state transition code
    
    - check the state transition; don't be surprised by NULL when STF_FATAL
      or STF_IGNORE
    
    - pass the now non-NULL state transition into
      success_v2_state_transition()
    
    - drop if(ST!=NULL) guards when ST must be non-NULL
    
    - after deleting ST, zap MD.ST, ST, and IKE
    
    - replace PST with IKE
    
    - update debug-logging
