[PATCH] AdvancedFeaturePkg/BmcElog: Change arithmetic logic

[Zhang, Shenglei]

Change the value from "sizeof(UINT8)" to 1 in the arithmetic expression.
The original value added to (UINT8 *)&GetBmcGlobalEnables is
(sizeof(UINT8)*sizeof(UINT8)) which equals to 1, so the functionality
looks right. But the arithmetic logic is actually wrong.
