[IBAL] compare TID based on user contolled area only

The current MAD processing code operates as follows when sending a request and trying to match a received response:

1. It saves the user's transaction ID (TID) to client_tid.
2. It clears the upper 32-bits of the TID.
3. It sets the upper 32-bits of the TID to an internal index.
4. It clears the upper 32-bits of a received response.
5. It tries to match the received response against client_tid.

Responses are only matched successfully if the user has already cleared the upper 32-bits of the TID before sending the MAD.  It would be better to only match responses using the lower, user-controlled, 32-bits of the TID.
