Actually this and the netfilter change break the build.

I'm reverting all of these rhashtable changes, please fix this stuff
up.

Firstly, the hash_rnd change results in this:

lib/rhashtable.c: In function ‘obj_raw_hashfn’:
lib/rhashtable.c:84:9: warning: passing argument 1 of ‘lockdep_rht_mutex_is_held’ discards ‘const’ qualifier from pointer target type [enabled by default]
lib/rhashtable.c:57:5: note: expected ‘struct rhashtable *’ but argument is of type ‘const struct rhashtable *’

Next, the netfilter change results in:

ERROR: "rhashtable_walk_start" [net/netfilter/nft_hash.ko] undefined!
