ligd bc17563a8f wqueue: fix race-condition on work_queue 
CPU0                     CPU1

work_queue(a)            work_queue(a)
                         -> work_cancel(a)
-> work_cancel(a)
-> enter_critical()
-> sq_addlast(a)
-> leave_critical()
                         -> enter_critical()
                         -> sq_addlast(a) // double add, wrong
                         -> leave_critical()

Also, this happens in mulit-threads in one CPU.

Fix:

work_cancel() should in critical section.
