migration: Don't try and recover return path in non-postcopy
In normal precopy we can't do reconnection recovery - but we also don't need to, since you can just rerun migration. At the moment if the 'return-path' capability is on, we use the return path in precopy to give a positive 'OK' to the end of migration; however if migration fails then we fall into the postcopy recovery path and hang. This fixes it by only running the return path in the postcopy case.
