x86/mce: Don't print MCEs when mcelog is active
BugLink: http://bugs.launchpad.net/bugs/1682130
commit
cc66afea58f858ff6da7f79b8a595a67bbb4f9a9 upstream.
Since:
cd9c57cad3fe ("x86/MCE: Dump MCE to dmesg if no consumers")
all MCEs are printed even when mcelog is running. Fix the regression to
not print to dmesg when mcelog is running as it is a consumer too.
