x86, microcode, AMD: Check before applying a patch
Make sure we're actually applying a microcode patch to a core which really needs it. This brings only a very very very minor slowdown on F10: 0.032218828 sec vs 0.056010626 sec with this patch. And small speedup on F15: 0.487089449 sec vs 0.180551162 sec (from perf output). Also, fixup comments while at it.
