zhushengle bcec32e389 fix: 延时队列为NULL时，返回的响应时间为64位最大值，导致无法更新tick timer的响应周期 
问题描述：
  当g_schedResponseTime = OS_SCHED_MAX_RESPONSE_TIME，且nextExpireTime =（UINT64-1时,
  表示系统的延时队列已为NULL,　此时tick timer 中应该设置为最大值，但由于判断
  g_schedResponseTime - nextExpireTime >= OS_CYCLE_PER_TICK,导致条件不成立，直接返回，
  无法将其设置为最大值，导致tick 中断一直频繁响应。
解决方案：
  将延时队列为NULL时的返回值以及idle线程的时间片修改为OS_SCHED_MAX_RESPONSE_TIME - OS_CYCLE_PER_TICK,
  保证延时队列为NULL，能够正常设置tick响应的最大值。
