[PATCH 0/2] netfilter: code refine for using new interface 'list_for_each_entry_continue_rcu'

From: Michael Wang <redacted>

Since 'list_for_each_continue_rcu' has been replaced with the new interface
'list_for_each_entry_continue_rcu' by commit 6705e86, we can no longer saving
code by passing 'list_head' to nf_iterate() and nf_queue() any more.

This patch set will pass 'nf_hook_ops' instead of 'list_head' to nf_iterate()
and nf_queue() as the parameter and saving some code.

Tested:
	add rule to iptables and check result by ping.
	nfqnl_test which is a test utility of libnetfilter_queue.
