[PATCH 6.1.y 1/2] mptcp: make pm_remove_addrs_and_subflows static

["Matthieu Baerts (NGI0)" <matttbe@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

commit e38b117d7f3b4a5d810f6d0069ad0f643e503796 upstream.

mptcp_pm_remove_addrs_and_subflows() is only used in pm_netlink.c, it's
no longer used in pm_userspace.c any more since the commit 8b1c94da1e48
("mptcp: only send RM_ADDR in nl_cmd_remove"). So this patch changes it
to a static function.
