3.8.13.14 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Renninger <trenn@suse.de>

commit 11f918d3e2d3861b6931e97b3aa778e4984935aa upstream.

Do it the same way as done in microcode_intel.c: use pr_debug()
for missing firmware files.

There seem to be CPUs out there for which no microcode update
has been submitted to kernel-firmware repo yet resulting in
scary sounding error messages in dmesg:

  microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin
