dnsmasq does not forward all of the received queries although it does in previous versions.

Issue

• dnsmasq does not forward all of the received queries although it does in previous versions.
• When dnsmasq received the same queries in a short period of time, some of the queries were not forwarded to outside nameservers.

• By checking dnsmasq.log, it looks like dnsmasq not forwarding all of received query like below.
