netfilter: nf_tables: fix scheduling-while-atomic splat
nf_tables_check_loops() can be called from rhashtable list walk so cond_resched() cannot be used here. Fixes: 81ea01066741 ("netfilter: nf_tables: add rescheduling points during loop detection walks") Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
