x86/MCE: Dump MCE to dmesg if no consumers

Browse source

When there are no error record consumers registered with the kernel, the
only thing that appears in dmesg is something like:

  [  300.000326] mce: [Hardware Error]: Machine check events logged

and the error records are gone. Which is seriously counterproductive.

So let's dump them to dmesg instead, in such a case.
