s390/net: Delete useless checks before function calls
Author: Markus Elfring <elfring@users.sourceforge.net>
The function debug_unregister() tests whether its argument is
NULL and then returns immediately. Thus the test around the call
is not needed.
This issue was detected by using the Coccinelle software.
