e2df52390a SMP: fix crash when switch to new task which is still running 
Situation:

Assume we have 2 cpus, and busy run task0.

CPU0                                CPU1
task0 -> task1                      task2 -> task0
1. remove task0 form runninglist
2. take task1 as new tcb
3. add task0 to blocklist
4. clear spinlock
                                    4.1 remove task2 form runninglist
                                    4.2 take task0 as new tcb
                                    4.3 add task2 to blocklist
                                    4.4 use svc ISR swith to task0
                                    4.5 crash
5. use svc ISR swith to task1

Fix:
Move clear spinlock to the end of svc ISR

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
