[PATCH v2 15/17] IB/mlx4: Delete unwanted spaces behind usages of the sizeof operator

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 21 Apr 2017 19:11:59 +0200

* Replace the source code "sizeof (" by "sizeof("
  according to the Linux coding style convention.

* Adjust indentation at a few places.
