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

[ Upstream commit 6eaf41e8 ]

Skip bound chain when flushing table rules, the rule that owns this
chain releases these objects.

Otherwise, the following warning is triggered:

  WARNING: CPU: 2 PID: 1217 at net/netfilter/nf_tables_api.c:2013 nf_tables_chain_destroy+0x1f7/0x210 [nf_tables]
  CPU: 2 PID: 1217 Comm: chain-flush Not tainted 6.1.39 #1
  RIP: 0010:nf_tables_chain_destroy+0x1f7/0x210 [nf_tables]
