[PATCH 5/5] IB/qib: Adjust two size determinations in qib_init_pportdata()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 5 Apr 2017 15:00:44 +0200

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

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