Fix the way RAID meta LVs are added to the dependency tree.

Browse Source 
Similar to the "mirror" segment type's log device, _add_dev_to_dtree should
be called and not _add_lv_to_dtree when adding metadata sub-LVs to the deptree.
Since _add_lv_to_dtree was being called, 'origin_only' could be set if a
snapshot sits on top of the RAID device.  This would cause the actual device
that needed to be added to be skipped in favor of the non-existant device,
"<foo>-real".
