libxt_connbytes: fix handling of --connbytes FROM
quoting man page:
match packets from a connection whose packets/bytes/average
packet size is more than FROM and less than TO bytes/packets. if
TO is omitted only FROM check is done.
But, when TO was omitted, we did treat it like "x:x" which is not
the same at all.
Before commit 09631dc60ce41bc484a42fcf4d4ddf7036820bd1
(libxt_connbytes: use guided option parser), we failed to parse
"--connbytes x" ('Bad range "x"'), but treated "x:" like "x:0xffffffff".
Also, restore the "from must be smaller than to" check.
