#1577093 — [PATCH 12/14] RDMA/cxgb4: Delete an unnecessary variable initialisation in create_qp()

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 8 Feb 2017 21:07:07 +0100

The local variable "ret" will be set to an appropriate value a bit later.
Thus omit the explicit initialisation at the beginning in this function.

The more clean approach will be to initialize this variable to -ENOMEM
and remove rest "ret = -ENOMEM" from the function.
