Ruiyu Ni 1c29d03869 UefiCpuPkg/MtrrLib: Fix MtrrDebugPrintAllMtrrsWorker to avoid hang
ARRAY_SIZE(Mtrrs->Variables.Mtrr) was used in
MtrrDebugPrintAllMtrrsWorker() to parse the MTRR registers.
Instead, the actual variable MTRR count should be used.
Otherwise, the uninitialized random data in MtrrSetting may cause
MtrrLibSetMemoryType() hang.

Steven Shi found this bug in QEMU when using Q35 chip.
