Taehee Yoo bbb8c61f97 netfilter: nf_tables: increase nft_counters_enabled in nft_chain_stats_replace() 
When a chain is updated, a counter can be attached. if so,
the nft_counters_enabled should be increased.

test commands:

   %nft add table ip filter
   %nft add chain ip filter input { type filter hook input priority 4\; }
   %iptables-compat -Z input
   %nft delete chain ip filter input

we can see below messages.
