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.

10529c7d0a sched: fix kasan report error when open CONFIG_DEBUG_MM
reason:
1. g_running_tasks = thread A
2. thread A exit (free thread A's tcb) -> thread B
3. thread B interrupt by irq
4. check g_running_tasks->flags -> kasan report used after free

rootcause:
g_running_tasks has't set completely when syscall hanppened

Resolve:
Use rtcb (get at ISR begining) instead
