mptcp: update set_flags interfaces
This patch updates set_flags interfaces, make it more similar to the
interfaces of dump_addr and get_addr:
mptcp_pm_set_flags(struct sk_buff *skb, struct genl_info *info)
mptcp_pm_nl_set_flags(struct sk_buff *skb, struct genl_info *info)
mptcp_userspace_pm_set_flags(struct sk_buff *skb, struct genl_info *info)
