Brian Barrett 01e8fc5f91 Redo of r12871, without the preconnect code change:
Move the req_mtl structure back to the end of each of the structures in 
the CM PML. The req_mtl structure is cast into a mtl_*_request_structure 
for each MTL, which is larger than the req_mtl itself. The cast will cause
the *_request to overwrite parts of the heavy requests if the req_mtl
isn't the *LAST* thing on each structure (hence the comment). This was 
moved as an optimization at some point, which caused buffer sends to fail...
