Subject: Reset ID of outgoing server link on DNS error correctly
X-Git-Tag: rel-17.1~3
X-Git-Url: https://arthur.barton.de/cgi-bin/gitweb.cgi?p=ngircd-alex.git;a=commitdiff_plain;h=60bb40d67a8d7c1e38a5d8ca2b7968cf08706008;ds=sidebyside

Reset ID of outgoing server link on DNS error correctly

Not resetting the ID prevents the daemon from trying to re-establish
outgoing server links when the DNS resolver failed to resole a hostname.
