common/WorkQueue: fix a race avoiding drain endless.

In function ShardedThreadPool::shardedthreadpool_worker, when call
_proces, it don't get shardedpool_lock. So there is a race between
return_waiting_threads and _proces. If return_waiting_threads first run
and _process will lost this signal and wait until.
This may cause ShardedThreadPool::drain can't complete.
