There is a chance to delete not yet delivered I/O interrupts if an exploiter uses the subsystem identification word 0x0000 while processing a KVM_DEV_FLIC_CLEAR_IO_IRQ ioctl. -EINVAL will be returned now instead in that case. Classic interrupts will always have bit 0x10000 set in the schid while adapter interrupts have a zero schid. The clear_io_irq interface is only useful for classic interrupts (as adapter interrupts belong to many devices). Let's make this interface more strict and forbid a schid of 0.
