[PATCH] ocfs2: dlm recovery fixes
when starting lock mastery (excepting the recovery lock) wait on any nodes
needing recovery. fix one instance where lock resources were left attached
to the recovery list after recovery completed. ensure that the node_down
code is run uniformly regardless of which node found the dead node first.
