UefiCpuPkg/MtrrUnitTest: Update UnitTestMtrrGetDefaultMemoryType.
Update UnitTestMtrrGetDefaultMemoryType for the case the when Fixed
MTRRs are not supported.
The original implementation returns FALSE when either fixed MTRR isn't
supported or the number of variable MTRRs is 0. The correct behavior
should return FALSE only when both fixed MTRR isn't supported and the
number of variable MTRRs is 0.
