After a channel is enabled we start a SENSE_ID command using
the SSCH instruction to recognize the control unit and device.
This tests the success of SSCH, the I/O interruption and the TSCH
instructions.
The SENSE_ID command response is tested to report 0xff inside
its reserved field and to report the same control unit type
as the cu_type kernel argument.
Without the cu_type kernel argument, the test expects a device
with a default control unit type of 0x3832, a.k.a virtio-net-ccw.
