ligd 415fe60695 signal: use work_cancel_sync() to fix used after free 
bug:

user thread:                             hpwork:
timer_create() with SIGEV_THREAD
timer_settime()
    irq -> work_queue()                  add nxsig_notification_worker to Q
timer_delete()
    nxsig_cancel_notification()
                                         call nxsig_notification_worker()
    work_cancel()
    timer_free()
                                         nxsig_notification_worker() used after free

root cause:
work_cancel() can't cancel work completely, the worker may alreay be running.

resolve:
use work_cancel_sync() API to cancel the work completely
