A state transition from closing state SMC_PEERFINCLOSEWAIT to closing state SMC_APPFINCLOSEWAIT is not allowed. Once a closing indication from the peer has been received, the socket reaches state SMC_CLOSED. And receiving a peer_conn_abort just changes the state of the socket into one of the states SMC_PROCESSABORT or SMC_CLOSED; sending a peer_conn_abort occurs in smc_close_active() for state SMC_PROCESSABORT only.
