locator::reconnectable_snitch_helper: don't check messaging_service version

Don't demand the messaging_service version to be the same on both
sides of the connection in order to use internal addresses.

Upstream has a similar change for CASSANDRA-6702 in commit a7cae32 ("Fix
ReconnectableSnitch reconnecting to peers during upgrade").
