This special case was not handled\ncorrectly by the code handling the later TCP socket close,\ncausing a NULL dereference crash in siw_cm_work_handler()\nwhen dereferencing a NULL listener. We now also cancel\nthe useless MPA timeout, if immediate MPA request\nprocessing fails.\n\nThis patch furthermore simplifies MPA processing in general:\nScheduling a useless TCP socket read in sk_data_ready() upcall\nis now surpressed, if the socket is already moved out of\nTCP_ESTABLISHED state."
