Ishizaki Kou 7a62755821 spidernet: improve interrupt handling
We intend this patch to improve spidernet interrupt handling to be
more strict.  We had following problem and this patch solves it.

 -when CONFIG_DEBUG_SHIRQ=y, request_irq() calls handler().
 -when spider_net_open() is called, it calls request_irq() which calls
  spider_net_interrupt().
 -if some specific interrupt bit is set at this timing, it calls
  netif_rx_schedule() and spider_net_poll() is scheduled.
 -spider_net_open() calls netif_poll_enable() which clears the bit
  __LINK_STATE_RX_SCHED.
 -when spider_net_poll() is called, it calls netif_rx_complete() which
  causes BUG_ON() because __LINK_STATE_RX_SCHED is not set.
