UefiCpuPkg/MtrrLib: Fix an assertion bug
0 40 f0 100
+---WT--+--UC--+--WT--+-----WB----+----UC----+
When calculating the shortest path from 0 to 100, the
MtrrLibCalculateLeastMtrrs() is called to update the
Vertices.Previous.
When calculating the shortest path from 0 to 40,
MtrrLibCalculateLeastMtrrs() is called recursively to update the
Vertices.Previous.
The second call corrupt the Previous value that will be used
later.
The patch removes the code that corrupts Previous.
