Because one can use a UC QP as a sender only sending any ack (at least 
on this QP).
But to be honest, i have a second thought on the check of the transport 
type of the QP:
maybe the CM should deny any setting of non reversible path for any QP,
to let know the user that there may be a problem with this path ...

what do you think?
