[PATCH 14/29] IB/mlx4: Delete an unnecessary variable in __mlx4_ib_query_gid()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 18 Feb 2017 15:04:50 +0100

* Call the function "memset" directly in an if branch without using
  an intermediate variable.

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