Fix ExecuteFinalHltInstruction function in f15h family code

Current ExecuteFinalHltInstruction function doesn't work well.
    (at least in configuration
    Supermicro board with Orochi AMD Opteron processors (model OS6234WKTCGGU))

System reboots when trying to halt core 2,4,6,8 or 10
    (OS6234WKTCGGU is 12 core processor)
    Based on this information, i think that code doesn't really work with
    f15 compute unit (CU) system.

Replacing ExecuteFinalHltInstruction function with
    analogous function from f15tn family code fix this problem.
    Both functions written from the same cahalt.asm file, but f15tn version
    seems more completed
