    ikev2: flatten code logging no-microcode errors
    
    Use a series of if() vis:
    
       if (case) {
          log
          possibly respond
          complete transition
          return
       }
    
    For each case be more selective about the error fed to complete
    transition code and what response if any:
    
    - only respond with INVALID_SYNTAX when an unprotected IKE_SA_INIT
      request
    
    - when a protected message is invalid, STF_FATAL the IKE SA (and
      possibly send back INVALID_SYNTAX) - this is going no where, for
      instance on the initiator, discarding the message and then
      re-transmitting is just going to get back the same invalid response.
