Subject: [PATCH v3 6/6] InfiniBand-ocrdma: Delete an unnecessary variable in
 ocrdma_dealloc_pd()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 14 Jan 2016 18:08:08 +0100

1. Return zero in one case directly.

2. Return the value from a call of the _ocrdma_dealloc_pd() function
   without using an extra assignment for the local variable.

3. Remove the variable "status" in this function then.
