[PATCH] netfilter: nat: constify rhashtable_params

[PATCH] netfilter: nat: constify rhashtable_params

[Arvind Yadav]

rhashtable_params are not supposed to change at runtime. All
Functions rhashtable_* working with const rhashtable_params
provided by <linux/rhashtable.h>. So mark the non-const structs
as const.

Actually, I tossed this. NAT rhashtable has been reverted, so no need
for this constification anymore.
