workqueue: clear leftover flags when detached
When a worker is detached, the worker->flags may still have WORKER_UNBOUND
or WORKER_REBOUND, it is OK for all cases:
1) if it is a normal worker, the worker will be dead, it is OK.
2) if it is a rescuer, it may re-attach to a pool with this leftover flag[s],
it is still correct except it may cause unneeded wakeup.
It is correct but not good, so we just remove the leftover flags.
