[PATCH 10/29] netfilter: nf_conntrack: restore nf_conntrack_htable_size as exported symbol

[Pablo Neira Ayuso]

This is required to iterate over the hash table in cttimeout, ctnetlink
and nf_conntrack_ipv4.

>> ERROR: "nf_conntrack_htable_size" [net/netfilter/nfnetlink_cttimeout.ko] 
>> undefined!
   ERROR: "nf_conntrack_htable_size" [net/netfilter/nf_conntrack_netlink.ko]

   ERROR: "nf_conntrack_htable_size" [net/ipv4/netfilter/nf_conntrack_ipv4.ko] 
undefined!
