[PATCH 11/17] s390/debug: Fix indentation in 13 functions

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 1 Sep 2016 23:05:51 +0200

The script "checkpatch.pl" can point the following information out.

ERROR: code indent should use tabs where possible

Thus fix the affected source code places.
