[PATCH net-next 04/12] mptcp: pm: only fill id_avail_bitmap for in-kernel pm

[Matthieu Baerts (NGI0)]

From: Geliang Tang <tanggeli...@kylinos.cn>

id_avail_bitmap of struct mptcp_pm_data is currently only used by the
in-kernel PM, so this patch moves its initialization operation under
the "if (pm_type == MPTCP_PM_TYPE_KERNEL)" condition.
