netfilter: nf_tables: adjust lockdep assertions handling
[ Upstream commit 8df1b40de76979bb8e975201d07b71103d5de820 ]
It's needed to check the return value of lockdep_commit_lock_is_held(),
otherwise there's no point in this assertion as it doesn't print any
debug information on itself.
Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool.
Fixes: b04df3da1b5c ("netfilter: nf_tables: do not defer rule destruction via call_rcu")
