From: Christof Schmitt <christof.schmitt@de.ibm.com>

When a FSF physical close returns the status boxed, this means that
another system already closed the port. For our system this is the
same status as in the good path, we have to send the normal close. So,
set the status for the boxed response to the same as for the good
status.
