This is necessary for the case when qxl is sharing irq line with a device A in a crash kernel. If qxl is initialized before A and A's irq was raised during this gap, returning IRQ_HANDLED in this case will cause this irq to be raised again after EOI since kernel think it was handled but in fact it was not.
