[ofa-general] Two element types on cancel_list in cancel_mads()?

I was looking at the local_list handling in cancel_mads() and the rest 
of mad code myself.  Hal knows this part of the code better than I do, 
maybe he can look here and see if there's a definite problem.  This 
looks like the cause of the bug Dotan just reported.
