ocfs2: Abstract out a debugging function for underlying dlms.

Browse Source 
dlmglue.c was still referencing a raw o2dlm lksb in one instance.  Let's
create a generic ocfs2_dlm_dump_lksb() function.  This allows underlying
DLMs to print whatever they want about their lock.

We then move the o2dlm dump into stackglue.c where it belongs.
