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.
