Fix heap size programming.

Browse Source 
- In various scenarios code was not programming the max heap size correctly
- It was possible for SSH to overcome the limit
- Size was programmed smaller then it really was, which resulted in smaller
reuse, which led to SBA reprogramming which led to lower performance in ooq
scenarios
- This change fixes the heap size programming by always utilizing full
allocation size and always limiting SSH at proper value
