[PATCH] s390/extmem: Use kmalloc_array() in dcss_set_subcodes()

From: Markus Elfring <redacted>
Date: Sat, 3 Sep 2016 16:06:05 +0200

* A multiplication for the size determination of a memory allocation
  indicated that an array data structure should be processed.
  Thus use the corresponding function "kmalloc_array".

* Replace the specification of a data type by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.
