[mjmartin] 44481: [ntoskrnl\config] - Description of what previous code was doing in commit r44469 was completely incorrect. Source prior to r44469 was only missing parentheses. - CmpSplitLeaf: Revert back to previous code with correct fix. Fireballs code was correct, and because I found it before him I save myself from a severe lashing.

- Description of what previous code was doing in commit r44469 was completely incorrect. Source prior to r44469 was only missing parentheses. 
- CmpSplitLeaf: Revert back to previous code with correct fix. Fireballs code was correct, and because I found it before him I save myself from a severe lashing.
