RADIUS client: Trigger failover more quickly if socket is not valid

Browse source 
It is possible for the connect() call to fail (e.g., due to unreachable
network based on local routing table), so the current auth/acct_sock may
be left to -1. Use that as an addition trigger to allow server failover
operation to be performed more quickly if it is known that the
retransmission attempt will not succeed anyway.
