s390/ap: add error response code field for ap queue devices
On AP instruction failures the last response code is now
kept in the struct ap_queue. There is also a new sysfs
attribute showing this field (enabled only on debug kernels).
Also slight rework of the AP_DBF macros to get some more
content into one debug feature message line.
