Subject: [PATCH 2/3] x86, ucode-amd: Don't warn when no ucode is available
 for a CPU revision

There is no point in warning when there is no ucode available for a
specific CPU revision. Currently the container-file, which provides the
AMD ucode patches for OS load, contains only a few ucode patches.

It's already clearly indicated by the printed patch_level whenever new
ucode was available and an update happened. So the warning message is
of no help but rather annoying on systems with many CPUs.
