RADIUS client: Do not try to send message without socket

Browse Source 
It is possible for the RADIUS authentication/accounting socket to not be
open even if partial RADIUS server configuration has been done through
the control interface SET commands. Previously, this resulted in send()
attempt using fd=-1 which fails with bad file descriptor. Clean this up
by logging this as a missing configuration instead of trying to send the
message when that is known to fail.
