Subject: [PATCH] marsadm: directly switch back to former primary

Use the new knowledge about old primary.

This is only relevant for people who are consistently ignoring
mars-manual.pdf which clearly states that intermediate
"marsadm secondary" should not be used at all, except for the
last step in final destruction of a resource.
