Recent changes in topology restricted the get_dc/get_rack calls. Older
code was trying to locate the endpoint in gossiper, then in system
keyspace cache and if the endpoint was not found in both -- returned
"default" location.
New code generates internal error in this case. This approach already
helped to spot several BUGs in code that had been eventually fixed, but
echoes of that change still pop up.
This patch relaxes the "missing endpoint" case by printing a warning in
logs and returning back the "default" location like old code did.
