The properties of netfilter object could be changed by 'qom-set' command, but the output of 'info network' command is not updated, because it got the old information through nf->info_str, it will not be updated while we change the value of netfilter's property.
Here we split a the helper function that could colletct the output information for filter, and also remove the useless member 'info_str' from struct NetFilterState.
