From: Geliang Tang <tanggeliang@kylinos.cn>

The output formats of 'ip mptcp' commands are much different from that
of 'pm_nl_ctl' commands.

A new 'change_address' helper is added here, to change the flag of an
address. This is a bit similar to mptcp_join.sh's pm_nl_change_endpoint().

Usage:
	Address ID - pm_nl_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.
