--------------------------------

[ Upstream commit 0ebc1064 ]

Bail out with EOPNOTSUPP when adding rule to bound chain via
NFTA_RULE_CHAIN_ID. The following warning splat is shown when
adding a rule to a deleted bound chain:

 WARNING: CPU: 2 PID: 13692 at net/netfilter/nf_tables_api.c:2013 nf_tables_chain_destroy+0x1f7/0x210 [nf_tables]

 RIP: 0010:nf_tables_chain_destroy+0x1f7/0x210 [nf_tables]
