genirq: Fix comment describing suspend_device_irqs()

The kerneldoc comment describing suspend_device_irqs() is currently misleading, because generally the function doesn't really disable interrupt lines at the chip level. Replace it with a more accurate one. Signed-off-by: Rafael J. Wysocki <[email protected]> LKML-Reference: <[email protected]> Signed-off-by: Thomas Gleixner <[email protected]>
