Borislav Petkov 6b0f43ddfa x86, AMD: Disable wrongly set X86_FEATURE_LAHF_LM CPUID bit
fbd8b1819e turns off the bit for
/proc/cpuinfo. However, a proper/full fix would be to additionally
turn off the bit in the CPUID output so that future callers get
correct CPU features info.

Do that by basically reversing what the BIOS wrongfully does at boot.
