From: Ralf Lici <r...@mandelbit.com>

During a float operation, we remove the old `mroute` object
corresponding to the current multi instance from the hash table and
insert a new one. With the introduction of the multi-socket feature, the
`mroute` structure gained a `proto` field, which must also be set in the
new instance, otherwise, hash table lookups will fail.

This commit ensures that the `proto` field is propagated from the
original to the new `mroute` object during float processing.
