From: Geliang Tang <tanggeliang@kylinos.cn>

The first parameter "skb" in mptcp_pm_nl_set_flags() is only used to
obtained the network namespace, which can also be obtained through the
second parameters "info" by using genl_info_net() helper. This patch
drops these useless parameters "skb" in all three set_flags() interfaces.
