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.
