Subject: [PATCH 3/8] x86/mce: Fix order of AMD MCE init function call

From: Aravind Gopalakrishnan <Aravind.Gopalakrishnan@....com>

In mce_amd_feature_init() we take decisions based on mce_flags being set
or not. So the feature detection using CPUID should naturally be ordered
before we call mce_amd_feature_init().

Fix that here.
