From: Yu Kuai <yukuai3@huawei.com>
md_wakeup_thread() can handle the case that pass in md_thread is NULL, the only difference is that md_wakeup_thread() will be called when current timeout is 'MAX_SCHEDULE_TIMEOUT', this should not matter because timeout_store() is not hot path, and the daemon process is woke up more than demand from other context already.
This patch prepare to factor out a helper to set timeout.
