netfilter: nf_tables: skip immediate deactivate in _PREPARE_ERROR



[ Upstream commit 0a771f7b ]

On error when building the rule, the immediate expression unbinds the
chain, hence objects can be deactivated by the transaction records.

Otherwise, it is possible to trigger the following warning:

 WARNING: CPU: 3 PID: 915 at net/netfilter/nf_tables_api.c:2013 nf_tables_chain_destroy+0x1f7/0x210 [nf_tables]
 CPU: 3 PID: 915 Comm: chain-bind-err- Not tainted 6.1.39 #1
 RIP: 0010:nf_tables_chain_destroy+0x1f7/0x210 [nf_tables]
