Add verbose error output for when unexpected i/o errors happen. This eases the
burden of debugging and reporting i/o errors. No error information is printed
in the success case, here is an example of what is output on error:
cio device error
ssid : 0x0000000000000000
cssid : 0x0000000000000000
sch_no: 0x0000000000000000
Interrupt Response Block Data:
Function Ctrl : [Start]
Activity Ctrl : [Start-Pending]
Status Ctrl : [Alert] [Primary] [Secondary] [Status-Pending]
Device Status : [Unit-Check]
Channel Status :
cpa=: 0x000000007f8d6038
prev_ccw=: 0x0000000000000000
this_ccw=: 0x0000000000000000
Eckd Dasd Sense Data (fmt 32-bytes):
Sense Condition Flags :

The Sense Data section is currently only printed for ECKD DASD.
