Subject: [PATCH 20/29] netfilter: nf_tables: Use nla_put_be32() to dump immediate parameters

nft_dump_register() should only be used with registers, not with
immediates.

Fixes: cb1b69b0b15b ("netfilter: nf_tables: add hash expression")
Fixes: 91dbc6be0a62("netfilter: nf_tables: add number generator expression")
