UefiCpuPkg/MtrrLib: Revert "Skip MSR access when the pair is invalid"
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1187
The patch reverts 9c8c4478cfcacaf5fd60b75ff78d26732d93a5b8
"UefiCpuPkg/MtrrLib: Skip Base MSR access when the pair is invalid".
Microsoft Windows will report an error in event manager if MTRR
usage is different across hibernate even when the difference is
in an non valid MTRR pair. This seems like a bug in Windows but
for compatibility and servicing reasons we think a change in UEFI
would wise.
A Windows change has already been submitted for the next iteration
(2019 time frame).
