If we detect that the internally manged state of the subchannel
is broken beyond repair while in do_subchannel_work in case of
virtual we just abort the operation and pretend all went well,
while in case of pass-through we honor the situation with -ENODEV
which results in cc 3 for the instruction whose handler triggered
the call.
Let's be consistent on this and do the -ENODEV also for virtual
subchannels.
