From: Geliang Tang <tanggeliang@kylinos.cn>

Just like set_limits() helper, this patch adds another one get_limits() to
show the limits.

Usage:
	Set limits - set_limits $ns $addrs $subflows
	Get limits - get_limits $ns

Use this new helper in pm_netlink.sh to replace all 'pm_nl_ctl limits'
commands.
