s390/pai: Calculate size of reserved PAI extension control block area 



The PAI extension 1 control block area is 512 bytes in total.
It currently contains three address pointer which refer to counter
memory blocks followed by a reserved area.
Calculate the reserved area instead of hardcoding its size. This
makes the code more readable and maintainable.
No functional chance.
