[PATCH 23/26] IB/ocrdma: Delete an unnecessary variable in ocrdma_dealloc_pd()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 8 Mar 2017 10:58:34 +0100

1. Return zero in one case directly.

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

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