sched/event: fix event bug after csection was removed

Browse Source 
Change:
    Replace list_delete_init() with list_delete() in nxevent_post.
  Reason:
    PR 16933 removed list_delete() in nxevent_wait() and  allow other task
    to preempt event-wait thread after list_add_tail() option,  the even-post thread
    can preempt it at this time and do  list_delete_init().

    The problem is that list_delete_init() will make  list_in_list() return true, so
    DEBUGASSERT(!list_in_list(&(wait->node))); will fail in nxevent_wait() after the event-wait thread
    returns.
