    Fix handle leaks when canceling LMT send requests
    
    If the destination of a LMT nonblocking send, which
    follows a rendez-vous protocol, receives the RTS packet to the
    unexpected queue followed by a cancelation request, the request in
    the unexpected queue never gets freed. To solve the issue, we
    forcefully free the rendez-vous request by adding an additional
    request release operation. Refs #287
