x86/microcode/AMD: Fix mixed steppings support
The AMD side of the loader has always claimed to support mixed
steppings. But somewhere along the way, it broke that by assuming that
the cached patch blob is a single one instead of it being one per
*node*.
So turn it into a per-node one so that each node can stash the blob
relevant for it.
[ NB: Fixes tag is not really the exactly correct one but it is good
enough. ]
