Subject: [PATCH 10/15] md-cluster: Delete an unnecessary variable
 initialisation in lockres_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 1 Oct 2016 13:07:52 +0200

The local variable "res" will be set to an appropriate pointer a bit later.
Thus omit the explicit initialisation at the beginning.
