Subject: [PATCH 12/13] s390: Use list_add_(before|after) macros

From: Ken Helias <kenhelias@...email.de>

Many places in the code uses list_add_tail/list_add to insert an entry
before/after another entry. This confuses the reader because these are usually
used to add an item to a list_head and not an entry. Better use the self
explaining function name.
