Subject: [PATCH 5.10 151/158] netfilter: nftables: fix a warning message in nf_tables_commit_audit_collect()

From: Dan Carpenter <dan.carpenter@...cle.com>

commit dadf33c9f6b5f694e842d224a4d071f59ac665ee upstream.

The first argument of a WARN_ONCE() is a condition.  This WARN_ONCE()
will only print the table name, and is potentially problematic if the
table name has a %s in it.

Fixes: c520292f29b8 ("audit: log nftables configuration change events once per table")
