ntp-4.2.4p5-rtnetlink.patch introduced an issue when using broadcast mode

Issue

• The NTP clients are configured as broadcast clients (using broadcastclient option in ntp.conf).
• If the network is restarted via service network restart while ntpd is running, the ntpd stops synchronizing:

Jun 12 12:20:09 ntpclient ntpd[2293]: Listening on interface #7 eth0, 172.16.121.171#123 Enabled

• ntpq -p returns "No association ID's returned".
