Pablo Neira Ayuso da107398cb netfilter: nf_tables: reject immediate NF_QUEUE verdict 
nft_queue is always used from userspace nftables to deliver the NF_QUEUE
verdict. Immediately emitting an NF_QUEUE verdict is never used by the
userspace nft tools, so reject immediate NF_QUEUE verdicts.

The arp family does not provide queue support, but such an immediate
verdict is still reachable. Globally reject NF_QUEUE immediate verdicts
to address this issue.

Fixes: f342de4e2f ("netfilter: nf_tables: reject QUEUE/DROP verdict parameters")
