Avoid starting DNSMASQ when in repeater mode

[ratcashdev]

Logs filled with 'watchdog 250:notify_rc start_dnsmasq' every 30 seconds if the device (AC68U) is in repeater mode. The condition seems to be wrong, fixed.

in repeater mode, dnsmasq is required when not connected, this is not a bug, please check your /jffs/configs and /jffs/scripts directories, delete the broken soft links or files, or delete all.

Both directories are empty. Maybe the logs are harmless, just found it strange, that I see those lines every 30 secs. Moreover, connections to this repeater are unstable. After-50-10 mins the connection loses INET and is unable to obtain an IP. Thought that's because logs fill up space and cause trouble.

5 mins? restart watchdog for no heartbeat, did you find this message in the log.

The following is a snippet from the log. This snippet repeats exactly every 15 mins.

I did not find the "restart watchdog" message in the logs.

less syslog.log | grep "restart" |wc -l

I have realized that start_dnsmasq is not working:

admin@RT-AC68U-B6E8:/tmp/home/root# service start_dnsmasq

Done.
admin@RT-AC68U-B6E8:/tmp/home/root# ps |grep dns
 4431 admin     1440 S    grep dns
