x86/microcode/amd: Do not overwrite final patch levels
A certain number of patch levels of applied microcode should not
be overwritten by the microcode loader, otherwise bad things
will happen.
Check those and abort update if the current core has one of
those final patch levels applied by the BIOS. 32-bit needs
special handling, of course.
See https://bugzilla.suse.com/show_bug.cgi?id=913996 for more
info.
