When adding a route fails because there is already a route with the same
(mask,value) in the tree, don't immediately return EEXIST.  Instead, check
to see if the pre-existing route was generated by protcol-cloning.  If so,
then it is OK to simply blow away the old route and re-attempt the insertion.
If not, then fall back to the same error code as before.
