netfilter: nf_tables: fix oops when deleting a chain with references
The following commands trigger an oops:
# nft -i
nft> add table filter
nft> add chain filter input { type filter hook input priority 0; }
nft> add chain filter test
nft> add rule filter input jump test
nft> delete chain filter test
We need to check the chain use counter before allowing destruction since
we might have references from sets or jump rules.
