afs: Don't skip server addresses for which we didn't get an RTT reading 

In the rotation algorithms for iterating over volume location servers and
file servers, don't skip servers from which we got a valid response to a
probe (either a reply DATA packet or an ABORT) even if we didn't manage to
get an RTT reading.
