[Patch addition] dm-log-cluster addendum1

[Jonathan Brassow <jbrassow@redhat.com>]

This patch is contains some 'type' corrections for the main
cluster log patch which is currently under review.

It cleans up the messages seen when compiling with 'V=1 C=1'
flags.

I don't envision this as a separate patch upstream, but rather
it should be rolled into the current dm-log-cluster.patch.
