extensions: hashlimit: fix incorrect burst in translations

iptables-translate -A INPUT -m tcp -p tcp --dport 80 -m hashlimit --hashlimit-above 200kb/s --hashlimit-burst 1mb --hashlimit-mode srcip,dstport --hashlimit-name http2 --hashlimit-htable-expire 3000 -j DROP

shows:

nft add rule ip filter INPUT tcp dport 80 flow table http2 { tcp dport . ip saddr timeout 3s limit rate over 200 kbytes/second burst 1 mbytes burst 6 packets} counter drop

which prints burst twice, this is not correct.
