[PATCH 3/5] IB/hfi1: Adjust another size determination in hfi1_user_sdma_alloc_queues()

[SF Markus Elfring <elfring-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org>]

From: Markus Elfring <elfring-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org>
Date: Fri, 10 Feb 2017 08:50:45 +0100

* Pass a product for a call of the function "vmalloc_user" without storing
  it in an intermediate variable.

* Delete the local variable "memsize" which became unnecessary with
  this refactoring.
