    kmsg_dump: don't run on non-error paths by default

comit a3dd3323 allows us to cleanly cherry-pick the actual fix, commit

== Impact ==

A high number of desktop and server systems are affected as well as many users.

== Test Case ==

A test kernel was built with these two patches and tested by original bug reporter as well as other bug commenter's, which were also affected by this bug.  These patches now allow the system to shutdown properly.
