netnet,netportnet: Fix value range support for IPv4

Ranges of values are broken with hash:net,net and hash:net,port,net.

hash:net,net
============

   # ipset create test-nn hash:net,net
   # ipset add test-nn 10.0.10.1-10.0.10.127,10.0.0.0/8

   # ipset list test-nn
   Name: test-nn
   Type: hash:net,net
   Revision: 0
   Header: family inet hashsize 1024 maxelem 65536
   Size in memory: 16960

   Members:
   10.0.10.1,10.0.0.0/8

   # ipset test test-nn 10.0.10.65,10.0.0.1
   10.0.10.65,10.0.0.1 is NOT in set test-nn.
   # ipset test test-nn 10.0.10.1,10.0.0.1
   10.0.10.1,10.0.0.1 is in set test-nn.

hash:net,port,net
=================

   # ipset create test-npn hash:net,port,net
   # ipset add test-npn 10.0.10.1-10.0.10.127,tcp:80,10.0.0.0/8
   # ipset list test-npn

   # ipset list test-npn
   # ipset test test-npn 10.0.10.126,tcp:80,10.0.0.2
   10.0.10.126,tcp:80,10.0.0.2 is NOT in set test-npn.
   # ipset test test-npn 10.0.10.126,tcp:80,10.0.0.0
   10.0.10.126,tcp:80,10.0.0.0 is in set test-npn.

   # ipset create test-npn hash:net,port,net
   # ipset add test-npn 10.0.10.0/24,tcp:80-81,10.0.0.0/8
   # ipset list test-npn

   10.0.10.0,tcp:80,10.0.0.0 is in set test-npn.

Correctly setup from..to variables where no IPSET_ATTR_IP_TO{,2}
attribute is given, so in range processing loop we construct proper
cidr value. Check whenever we have no ranges and can short cut in
hash:net,net properly. Use unlikely() where appropriate, to comply
with other modules.
