Subject: [PATCH v2 11/12] IB/ocrdma: Delete an unnecessary variable in
 ocrdma_dealloc_pd()

From: Markus Elfring <elfring@...rs.sourceforge.net>

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.
