[PATCH 2/3] x86: microcode: report if no microcode file was found

[Denys Vlasenko <dvlasenk@redhat.com>]

Before this change, successful microcode uploads clearly
indicate that it was done:

microcode: CPU1 sig=0x206a7, pf=0x10, revision=0x1a
microcode: CPU1 updated to revision 0x29, date = 2013-06-12

whereas if microcode was not uploaded, it is not clear why:

microcode: CPU1 sig=0x206a7, pf=0x10, revision=0x29
(nothing more)

So, what was it? No microcode file? No microcode for this sig/pf?
CPU already has microcode with this (or newer) revision?

In practice, it means that I heed to ask people to provide me
with more information ("do you have microcode package installed?
which version is it?").

This change upgrades existing message from pr_debug to pr_info,
which covers "no microcode file" case:

microcode: CPU1 sig=0x206a7, pf=0x10, revision=0x29
microcode: data file intel-ucode/06-2a-07 load failed
