From: Geliang Tang <tanggeliang@kylinos.cn>

This patch adds get_local_id() interface for struct mptcp_sched_ops,
then mptcp_pm_get_local_id() can directly invoke get_local_id() interface
through "ops" of "msk->pm". Instead of using mptcp_pm_is_userspace() to
check which get_local_id() helper to invoke.

Rename
	mptcp_pm_nl_get_local_id()/mptcp_userspace_pm_get_local_id()
to
	mptcp_pm_kernel_get_local_id()/mptcp_pm_userspace_get_local_id()

and make them static.
