Jiuzhu Dong dc1c7a644a wqueue: delete sem_wait to avoid race condition ... when work_cancel was called, we need to check work.timer whether is active by WDOG_ISACTIVE for work_queue with delay. The wdog cb has not been executed when the flag:active is cleared and if we check flag:active at this moment, WDOG_ISACTIVE will return false. so the work_cancel will sem_wait until post a semaphore, but all free hpwork_thread also wait this semphore and their priority are high than caller, this will be a race condition causing thread/task of calling work_cancel block.
