If the initial attempt at opening the socket connection to the RADIUS
server failed due to missing IP connectivity during startup, e.g., with
"connect[radius]: Network is unreachable", hostapd did not try to
reconnect when RADIUS messages were sent. Instead, it only reported "No
authentication server configured" even if the configuration did have a
server entry.
This was broken by commit 9ed4076673
('RADIUS client: Do not try to send message without socket') for the
initial case and the more recent fixes in RADIUS server failover cases
did not cover the initial failure case.
