[PATCH 19/26] IB/ocrdma: Improve another size determination in ocrdma_alloc_mr()

From: Markus Elfring <elfring-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org>
Date: Wed, 8 Mar 2017 09:54:42 +0100

Replace the specification of a data type by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
