x86/mce: Work around build warning after MSR-interface switch

The recent switch to 64-bit MSR interfaces introduced a build warning.

Work it around with a __maybe_unused annotation. After the full conversion
of the APIs we'll be able to address this more robustly by making sure
the APIs consume all the values as far the compiler is concerned, so that
the compiler doesn't emit such nuisance warnings.
