[PATCH v2 5/9] vfio/ccw: Clear error object pointer after non-fatal errors

[Eric Farman <farman@linux.ibm.com>]

Just like in vfio/ap, there is a non-fatal message that could be
generated, with a stale pointer in the error object variable.

Unlike vfio/ap, there is no secondary message that could attempt
to use it. Clear it in the same way, in case that ever changes.
