The address that needs to change flags can only be identified by an address
ID in change_endpoint() helper. This patch adds another helper named
change_address(), its 2nd parameter is an IP address.

Usage:
	Address ID - change_endpoint $ns id $id $flags
	IP address - change_address $ns $addr $flags

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

It is confusing, there is no 'change_endpoint' helper.
