[PATCH] s390: wrong interrupt delivered for hsch() or csch()
When cio waits for the interrupt for a basic sense, interrupts for hsch() or csch() issued in the meantime are wrongly counted as interrupts for the basic sense and the accumulated irb is passed to the device driver. In ccw_device_w4sense(), check for clear or halt function in the irb and pass the irb for the csch() or hsch() to the device driver.
